Updating multiple rows at a time in sql Chat rooms looking for milfs

Many thanks,,, IF 1-6 RECORDS comes from page 1 means how u stored that in table,do u maintain any Id for identify these records comes from this page? If it not so u should maintain a common Id for all pages.UPDATE summary_data SET current_category = (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id) WHERE EXISTS (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id); If you want to test your skills using the SQL UPDATE statement, try some of our practice exercises. So column1 would be assigned the value of expression1,column2 would be assigned the value of expression2, and so on. column1, column2The columns in the table to insert values.expression1, expression2The values to assign to the columns in the table. I need some assistance in writing an update sql query.

The whole table (all records are splitted in many web forms) it means page 1 contains 1-6 records to update, page 2 contains 7-10 records to update.The CTE result set is derived from a simple query and is referenced by UPDATE statement.Common table expressions can also be used with the SELECT, INSERT, DELETE, and CREATE VIEW statements.Table structure is like this Id Setting Name Value Setting Name contains the setting name, and value contains the actual value.Well to update mutiple rows in SQL you use an update statement and a where clause if the rows have something in common.

That may not sound like too useful a thing now, but the MERGE statement represents a very powerful way to bring a database table into sync with an external source of data (such as a flat file feed from a remote system). The value for DEPTNO should be 50, DNAME should be “PROGRAMMING”, and LOC should be “BALTIMORE”.
