SELECT * FROM example_timestamp; ---- -------------------------- --------------------- | id | data | cur_timestamp | ---- -------------------------- --------------------- | 1 | The time of creation is: | 2004-12-01 | ---- -------------------------- --------------------- 1 row in set (0.00 sec)mysql SELECT * FROM example_timestamp; ---- --------------------------- --------------------- | id | data | cur_timestamp | ---- --------------------------- --------------------- | 1 | The current timestamp is: | 2004-12-01 | ---- --------------------------- --------------------- 1 row in set (0.01 sec) retains its initial value and is not changed during subsequent updates.For versions prior to 4.1, the only workaround is to create two timestamp columns in a table, and explicitly set the second one when inserting the record.In other words, a target row shouldn't join to more than one row from the other table(s).

Common table expressions can also be used with the SELECT, INSERT, DELETE, and CREATE VIEW statements. If you omit the WHERE clause, all records in the table will be updated! The WHERE clause specifies which record(s) that should be updated.DEFAULT Specifies that the default value defined for the column is to replace the existing value in the column.This can also be used to change the column to NULL if the column has no default and is defined to allow null values.These exercises allow you to try out your skills with the UPDATE statement.You will be given questions that you need to solve.Oracle lets you write stored procedures and anonymous PL/SQL blocks that use dynamic SQL. DEFINE_COLUMN(curid, i, numvar); ELSIF desctab(i).col_type = 12 THEN DBMS_SQL. COLUMN_VALUE(curid, i, namevar); ELSIF (desctab(i).col_type = 2) THEN DBMS_SQL. CLOSE_CURSOR(curid); END; / CREATE OR REPLACE PROCEDURE DO_QUERY(mgr_id NUMBER) IS TYPE Cur Type IS REF CURSOR; src_cur Cur Type; curid NUMBER; sql_stmt VARCHAR2(200); ret INTEGER; empnos DBMS_SQL. Dynamic SQL statements are not embedded in your source program; rather, they are stored in character strings that are input to, or built by, the program at runtime. COLUMN_VALUE(curid, i, numvar); ELSIF (desctab(i).col_type = 12) THEN DBMS_SQL. Compound assignment operator: = Add and assign -= Subtract and assign *= Multiply and assign /= Divide and assign %= Modulo and assign &= Bitwise AND and assign ^= Bitwise XOR and assign |= Bitwise OR and assign Returns updated data or expressions based on it as part of the UPDATE operation.The SQL Server (Transact-SQL) UPDATE statement is used to update existing records in a table in a SQL Server database.
