Sql updating multiple rows with different values Mobile redtube free

We are going to update column DESCRIPTION and PICTURE in table Categories_Test by using data in table Categories, based on data in the common column CATEGORY_ID. Update data in a column in table A based on a common column in table B. Update data in two columns in table A based on a common column in table B. Conditionally update data in table A based on a common column in table B. No portion may be reproduced without my written permission.

The update query below shows that the PICTURE column is updated by looking up the same ID value in CATEGORY_ID column in table Categories_Test and Categories. If you need to update multiple columns simultaneously, use comma to separate each column after the SET keyword. Here we only want to update PICTURE column in Categories_Test table where the data in Category_Name column is Seafood in table Categories.

Hi I'm hoping one of you kind folk can help with this.

The sub-query must yield no more than one row when executed.

If it yields one row, its column values are assigned to the target columns; if it yields no rows, NULL values are assigned to the target columns.

Because of this indeterminacy, referencing other tables only within sub-selects is safer, though often harder to read and slower than using a join.

One thought on “sql updating multiple rows with different values”

  1. If a married but separated man takes a woman out for dinner, but drops her off at the end of the evening and goes his own way, it’s generally not adultery. If he dates that woman repeatedly and they begin spending time together in each other’s homes, this can open the door for his spouse to claim the affair is adulterous because sexual contact might be taking place.
