If this parameter is left empty, an error is reported. amount Length (in bytes for BLOBs) to delete as the IN parameter, or actual length deleted as the OUT parameter.
Return type: record pg_stat_get_sql_count() Description: Provides the counts of the SELECT, UPDATE, INSERT, DELETE, and MERGE INTO statements executed on the current node.
When limit_type is set to SQL_TYPE, the value of this parameter can be select, update, insert, delete, or merge. When limit_type is set to SESSION_ACTIVE_MAX_COUNT, the value of this parameter can only be CPU_OR_MEMORY. key_words No String Keyword.
Delete the primary key and foreign key constraints of a table. ALTER TABLE DROP [PRIMARY | FOREIGN]KEY - Support the CREATE TABLE... LIKE syntax. CREATE TABLE ... LIKE In versions earlier than MySQL 8.0.16, CHECK constraints are parsed but their functions are ignored.
Delete the primary key constraints of a table. ALTER TABLE - Support the CREATE TABLE ... LIKE syntax. CREATE TABLE ... LIKE In versions earlier than MySQL 8.0.16, CHECK constraints are parsed but their functions are ignored. In this case, CHECK constraints are not replicated.

If a function is defined as IMMUTABLE or SHIPPABLE, avoid INSERT, UPDATE, DELETE, MERGE, and DDL operations in the function because the CN needs to determine the execution node for these operations. Otherwise, an error may occur.
Operations such as SELECT, UPDATE, INSERT, and DELETE can be performed on XML data. The prerequisite is that you have connected to the database using the connection object conn.
The next 1-byte letter can be B, C, I, U, or D, representing BEGIN, COMMIT, INSERT, UPDATE, or DELETE, respectively. If B is used in Step 3: The next eight bytes (uint64) indicate the CSN. The next eight bytes (uint64) indicate first_lsn.

The DML statements include the UPDATE, INSERT, DELETE, MERGE, PREPARE, EXPLAIN, SHOW, LOCK, COPY, CLUSTER, ANONYMOUS, DELTA, EXECUTE, MOVE, FETCH, CLOSE, DEALLOCATE, DECLARE, and LOAD statements.
Otherwise, the performance of DML operations such as INSERT, UPDATE, and DELETE may be affected. Syntax Rename a table index. ALTER INDEX [ IF EXISTS ] index_name RENAME TO new_name; Change the tablespace to which a table index belongs.
If the third digit is 1, a delete operation is recorded. If the second digit is 1, an insert operation is recorded. Example: When enable_htap is set to off: gaussdb=# select * from gs_htap_tmu_data(16796,0); ERROR: Query failed due to ENABLE_HTAP is not enabled.
If you want to use EXPLAIN ANALYZE on an INSERT, UPDATE, DELETE, CREATE TABLE AS, or EXECUTE statement without letting the statement affect your data, use the following approach: START TRANSACTION; EXPLAIN ANALYZE ...; ROLLBACK; The DETAIL, NODES, and NUM_NODES parameters cannot be
This parameter is invalid for UPDATE and DELETE on old tuples, and the corresponding tuples always output the stored generated columns. Value range: Boolean.
VALUES(100, 10, 1000, 10000, 200, 2000); -- View data. b_database=# SELECT * FROM int_type_t2; a | b | c | d | e | f -----+----+------+--------+-----+------ 100 | 10 | 1000 | 10000 | 200 | 2000 (1 row) -- Drop the table. b_database=# DROP TABLE int_type_t2; -- Delete
If the UPDATE GLOBAL INDEX clause is not used when you delete, split, clear, or exchange partitions, concurrent DML services may report errors due to invalidated indexes.
CsnMinLock Used to control the concurrent access and storage of CSN MIN HypoIndexLock Used to create, delete and reset the virtual index by the lightweight lock. XGBoostLibLock Used by DB4AI to call the XGBoost library.
