Last Updated：2025-06-24 11:54:39 Updated

Editing area of SQL window

The toolbar in the editing area of SQL window supports the following functional keys:

Icon	Description
	Run all SQL statements in the current SQL window. All SQL statements can be run via the shortcut Ctrl+Enter.
	Runs all currently selected SQL statements or the SQL statement where the cursor is at. You can run the current statement through the shortcut key Ctrl+Shift+Enter.
	Click this icon to view the estimated execution plan (execution result of `EXPLAIN`) for the SQL statement that is selected or on which the pointer hovers. The displayed execution data may be slightly different from the data generated after statement execution. You can use this feature to evaluate an SQL statement. Click the Plan icon. On the Plan Details tab, click View Formatting Info to switch to the formatted view.
	Click this icon and enter text in the search field to find the specific content and enter text in the replacement field to replace the content found.
	Click this icon to undo the previous operation.
	Click this icon to reverse an Undo operation.
	Click this icon to apply formatting, such as indentation, line break, and keyword highlighting, to the selected SQL statements or all the SQL statements in the current SQL window.
	Click this icon to convert the copied rows or columns into the specified format during queries. After you paste the copied data to the SQL editing area, select the copied data and click IN Value Conversion to convert it into the `in('A','B')` format. Column values are separated with line breaks. Row values are separated with spaces or tabs.
	The system supports three capitalization formats: All Caps, All Lowercase, and Capitalize First Letter. Click this icon to convert the selected statements in the script to the corresponding capitalization format.
	You can add indents to or delete indents from the statements that you selected.
	You can click Add Comment to convert the statements that you select into comments or click Delete Comment to convert comments to SQL statements.
	Delimiter: Select the sign that you want to use as the delimiter from the drop-down list. Five types of delimiters are supported: semi-colons (;), slashes (/), double slashes (//), dollar signs ($), and double dollar signs ($$). Row Limit: Set the maximum number of lines that a query can return. Default value: `1000`. Retrieve Column Metadata: Choose whether to obtain information about columns in the result set before SQL execution. If the table contains a large number of columns, we recommend that you disable this option. After you disable this option, column comments and editable columns are not queried, which shortens the SQL execution time. Session Variable: You can edit, refresh, and search for variables.

Table

Table attribute management

Basic information

table-attribute1

Click Basic Information in the left-side navigation pane of the Attribute tab to view the basic information of the current table.

Parameter	Description
Table Name	Displays the name of the current table. You can rename the table here.
Default Character Set	Displays the character set that the table uses.
Default Sorting Rule	Displays the sorting rule that the table uses.
Description	Displays the description that you specified when you created the table. You can also modify the table description here.
Owner	Displays the database to which the table belongs.
Last Modified On	Displays the date on which the table was last modified.
Row Data Volume	Displays the number of rows in the table.
Size	Displays the size of data in the table.

Column information

table-attribute2

Field	Description
Name	The name of the column.
Type	The data type of the column.
Length	The length of the data type.
Scale	The number of decimal places of the data type.
Non-empty	Specifies whether the value of the column must be specified.
Auto-increment	Specifies whether to set the column to an auto-increment column. This parameter is valid in the MySQL compatible mode. Notice Only one auto-increment column is allowed for each table. After a column is set to an auto-increment column, the auto-increment checkbox of other columns cannot be selected.
Virtual Column	Specifies whether to set the column to a virtual column. Notice When you set a virtual column, you must specify its expression. When you create a virtual column, you must define an expression that the virtual column depends on. A virtual column is a generated column. A generated column can be a virtual generated column or a stored generated column. The value of a virtual column is calculated based on the expression only when the column is used. Therefore, when you insert data into the table, you cannot specify values for the virtual column.
Default Value/Expression	The default value or expression of the column.
Comment	The additional information about the column.

The following table describes operations that you can perform on the column setting page.

Operation	Description
Toolbar operations	You can add or delete columns by using the top toolbar of the page.
Click a row ID	- You can click a row ID to select the row and display the quick access toolbar that allows you to add or delete a row. - You can click a row ID to select the row, and then drag the row to adjust its order.
Right-click a row	You can right-click a row to select it, and then select Copy or Move Down from the context menu that appears.

Index information

table-attribute3

Field	Description
Index Name	The name of the index.
Scope	The default value is GLOBAL. Valid values: GLOBAL and LOCAL.
Method	The default value is BTREE, which is applicable to a global index. Valid values: Empty, BTREE, and HASH. A BTREE index stores data in a B+ tree structure, and is suitable for searching for SQL statements in the specified index scope. A HASH index is implemented based on a HASH table, and is used only when the query conditions exactly match all columns in the HASH index. A HASH index can be used only for query conditions that use the equal operator (=), IN operator, or NULL-safe equal operator (<=>). A HASH index cannot be used for sorting and is not suitable for columns with less distinctive values, such as the gender column.
Index Type	The default value is NORMAL. Valid values: NORMAL, UNIQUE, and FULLTEXT. NORMAL indicates a normal index. UNIQUE indicates a unique index that does not allow duplicate values, such as the emp_no column. FULLTEXT indicates a full-text index, which is used to search a table that contains a large amount of data.
Columns	The columns to be indexed. Pay attention to the order of the indexed columns.
Invisible	Specify whether the index is invisible.

Constraint information

table-attribute4

OceanBase Cloud supports different constraints in the MySQL compatible and Oracle compatible modes, and different constraints require different information. Therefore, you need to specify the required information based on the constraint you selected and the requirements on the page.

Field	Description
Constraint Name	The name of the constraint.
Column Information	The field or a group of fields specified as the constraint.
Associated Schema	The schema where the associated table is located when Foreign Key Constraint is used. The associated table is the parent table. This field is valid only in the Oracle compatible mode.
Associated Database	The database where the associated table is located when Foreign Key Constraint is used. The associated table is the parent table. This field is valid only in the MySQL compatible mode.
Associated Table	The associated table when Foreign Key Constraint is used. The associated table is the parent table.
Associated Field	The associated field when Foreign Key Constraint is used. The associated field is in the parent table.
Delete	Specifies the action to be performed on the current table when the data in the associated table is deleted. The current table is the child table, and the associated table is the parent table. The following four types of action are supported: CASCADE, NO ACTION, RESTRICT, and SET NULL. OceanBase Cloud supports different foreign key actions in the MySQL compatible and Oracle compatible modes. In the MySQL compatible mode, OceanBase Cloud allows you to specify CASCADE, NO ACTION, RESTRICT, and SET NULL. In the Oracle compatible mode, OceanBase Cloud allows you to specify CASCADE, NO ACTION, and SET NULL. Notice At present, OceanBase Cloud does not support SET NULL. For more information about the syntax, see Create a table, or the official documentation of MySQL or Oracle.
Update	Specifies the action to be performed on the current table when the data in the associated table is updated. The current table is the child table, and the associated table is the parent table. The following four types of action are supported: CASCADE, NO ACTION, RESTRICT, and SET NULL. OceanBase Cloud supports different foreign key actions in the MySQL compatible and Oracle compatible modes. In the MySQL compatible mode, OceanBase Cloud allows you to specify CASCADE, NO ACTION, RESTRICT, and SET NULL. In the Oracle compatible mode, OceanBase Cloud allows you to specify NO ACTION. Notice At present, OceanBase Cloud does not support SET NULL. For more information about the syntax, see Create a table, or the official documentation of MySQL or Oracle.
Check Condition	Specifies the check rules for data verification when Check Constraint is enabled.

Partition information

table-attribute5

The definition of a partition in the MySQL compatible mode is different from that in the Oracle compatible mode. So, the values of the following fields vary in different modes. You need to specify the following fields based on the selected partitioning method.

Field	Description
Partitioning Method	Specifies the partitioning method. The partitioning methods supported in the MySQL compatible mode are different from those in the Oracle compatible mode. Range partitioning: Multiple rows with column values in an ordered, continuous, and non-overlapping range are assigned to a partition. List partitioning: A table is partitioned based on the enumeration values. Hash partitioning: A table is partitioned based on a given number of partitions. For a table that stores data without a clear pattern or range, you can use hash partitioning to randomly distribute values of the partition column to different partitions based on the HASH algorithm. Key partitioning: This partitioning method is similar to HASH partitioning. The difference is that key partitioning only supports computation of one or more columns, and the MySQL server provides its own hash function. At least one INT type column is required for Key partitioning.
Field	The column that is used as the partition key.
Expression	Partitions are divided based on the return value of the expression. The partition expression is not supported in the Oracle compatible mode.
Partition	Based on the value specified for Partitioning Method, you may need to specify information such as Partition Name, Partition Quantity, Upper Limit, and Value Enumeration. You can add multiple partitions and drag selected fields to adjust their order.
