AUTO_INSERT procedure¶
Automatically inserts data into DEST_TABLE from SOURCE_TABLE.
Prototypes¶
AUTO_INSERT(SOURCE_SCHEMA VARCHAR(128), SOURCE_TABLE VARCHAR(128), DEST_SCHEMA VARCHAR(128), DEST_TABLE VARCHAR(128))
AUTO_INSERT(SOURCE_TABLE VARCHAR(128), DEST_TABLE VARCHAR(128))
Description¶
The AUTO_INSERT procedure inserts all data from SOURCE_TABLE into DEST_TABLE by means of an automatically generated INSERT statement covering all columns common to both tables.
If SOURCE_SCHEMA and DEST_SCHEMA are not specified they default to the current schema.
Only columns common to both the destination table and the source table will be
included in the generated statement. Destination columns must be updateable
(they cannot be defined as GENERATED ALWAYS), and the executing user must
have INSERT privileges on the destination table.
Parameters¶
- SOURCE_SCHEMA
- If provided, specifies the schema containing SOURCE_TABLE. If omitted, defaults to the value of the CURRENT SCHEMA special register.
- SOURCE_TABLE
- Specifies the name of the table within SOURCE_SCHEMA from which to read data.
- DEST_SCHEMA
- If provided, specifies the schema containing DEST_TABLE. If omitted, defaults to the value of the CURRENT SCHEMA special register.
- DEST_TABLE
- Specifies the name of the table within DEST_SCHEMA into which data will be copied.
