Updating entire tables using update query
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 Tom, Great to visit ask tom site i'm keep on learning oracle things here. i have loaded with "SRC_key = 16" new source data into tables which we used in this view. Short question: If I delete cca 3M entries from table of cca 6.5 rows (and 19 columns), would it be beneficial to re-index? Hello, I want to use TDE tablespace encryption on my database. The WHERE clause specifies which record(s) that should be updated.The SQL UPDATE statement is used to change data within columns of a SQL Server data table.Some of the common ones are: In these cases, the UPDATE statement execution stops and the UPDATE generates an error.No rows from the UPDATE statement are saved into the table, even those rows that didn’t generate an error.
