Updating a value with one from another table (1) By Gilles on 20:31:50 source Hello, I've done some reading and experimenting, but I can't figure out how to update a value from a value found in other table: Error: ambiguous column name: zip.CODESTAT UPDATE t1 SET ZIPCODEt2.ZIPCODE FROM t1,t2 WHERE t2.CODESTATt1. I guess/hope there is a simplier and more maintainable way to do that.SQLite UPDATE Query is used to modify the existing records in a table. We can update single columns as well as multiple columns using UPDATE statement as per our requirement. update update MyTable set vala (select x.vala from MyTable x where x.snapshotid 1 and x.objec. "Table1_id = (SELECT max(Table1_id) FROM Table1)", sourceRecord_idx, sourceRecord_idx, sourceRecord_idx) Īs you can see for each single field I must write its specific SET case and moreover the value for each filed is retrieved by a select. The UPDATE statement in SQL is used to update the data of an existing table in the database. update update MyTable set vala src.vala, valb src.valb, valc src.valc from (select from MyTable where snapshotid 1) as src where MyTable.objectid src.objectid and MyTable.snapshotid 2 2.

You should be able to replace this with another value like a GUID without affecting the application at all. "fiedl2 = case when fiedl2 is null then (SELECT fiedl2 FROM Table1 WHERE Table1_id = %d) else fiedl2 end, "\ "fiedl1 = case when fiedl1 is null then (SELECT fiedl1 FROM Table1 WHERE Table1_id = %d) else fiedl1 end, "\ I was wandering if it's possible to write a sql query that take a whole record from a table and update all NULL fields in another record of the same table. Moreover my code is very very unmanageable, because of if in the future the table structure will change I'll must rewrite the query to add or remove fields.
