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 & "".
In this syntax: First, specify the name of the table that you want to update data. Second, specify a list of column c1, c2, …, cn and the corresponding value v1, v2, … vn that need to be updated. Third, specify the condition to indicate which rows to be updated.
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
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.
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.
Updating Db2 data by using UPDATE statements. You can change the data in a table by using the UPDATE statement or the MERGE statement. The UPDATE statement modifies zero or more rows of a table, depending on how many rows satisfy the search condition that you specify in the WHERE clause.
An UPDATE statement will reset the AREO* state of a table if all conditions are true: The statement is a searched UPDATE statement. An UPDATE statement within a SELECT statement will not reset the AREO* state. The expression in the SET clause is not a scalar-fullselect or row-fullselect.
