17 Ιαν 2014 · I know there's a way to have insert statements within excel. Is there one for update? so far I've managed to come up with my update statement in SQL, but I have 6000 rows to update: = "Update table Set name = " & A1 & " Where namefk = " & E2 & "".
Changing data in a table using the UPDATE statement. To update data in a table or view, use the UPDATE statement. With the UPDATE statement, you can change the value of one or more columns in each row that meets the search condition of the WHERE clause.
Update fields: UPDATE tbl3 SET col1 = 5, mycol2 = 'e' -– all table UPDATE tbl3 SET col2 = 'd' WHERE col1 = 7 Merge (upsert): MERGE INTO tbl3 AS t USING (SELECT col1 FROM tbl1) s ON (t.col1 = s.col1) WHEN MATCHED THEN UPDATE SET col2 = 'X' WHEN NOT MATCHED THEN INSERT VALUES (10, 'X') Delete rows: DELETE FROM tbl1 -–all table
You can use an UPDATE or MERGE statement to specify the values that are to be updated in a single row. You can specify constants, host variables, expressions, DEFAULT, or NULL. Specify NULL to remove a value from a row's column (without removing the row).
The UPDATE statement updates the values of specified columns in rows of a table, view or nickname, or the underlying tables, nicknames, or views of the specified fullselect.
Syntax diagrams can be found in the SQL Reference of Db2 (or your prefered RDBMS). We only give you lots of examples how to use SQL. When you master this stuff, you should learn more and improve your knowledge using the "real" manuals.
