I tried to select some fields from a table and insert them from the stored procedure into the existing table. This is what I'm trying:
SELECT col1, col2 INTO dbo.TableTwo FROM dbo.TableOne WHERE col3 LIKE @search_key
I think select... Into... Is a temporary table, which is why I get the error that dbo.TableTwo already exists.
How to insert dbo.TableTwo from dbo.TableOne dbo.TableTwo?
Its working principle is as follows:
insert into Gengl_Del Select Tdate,DocNo,Book,GlCode,OpGlcode,Amt,Narration from Gengl where BOOK='" & lblBook.Caption & "' AND DocNO=" & txtVno.Text & ""
select * into existing table database..existingtable from database..othertables....
If you have used select * into tablename from other tablenames, you can select * into existing table tablename from other tablenames next time you want to append
Select... INTO... Is only valid if the table specified in the INTO clause does not exist - otherwise, you must use:
INSERT INTO dbo.TABLETWO SELECT col1, col2 FROM dbo.TABLEONE WHERE col3 LIKE @search_key
Suppose there are only two columns in dbo.TABLETWO - otherwise you need to specify the columns:
INSERT INTO dbo.TABLETWO (col1, col2) SELECT col1, col2 FROM dbo.TABLEONE WHERE col3 LIKE @search_key
There are two different ways to insert data from one table to another.
For existing tables - INSERT INTO SELECT
This method is used when you have previously created a table in the database and inserted data from another table into the table. If the columns listed in the insert clause and the select clause are the same, they do not need to be listed. It's a good habit to always list them for readability and scalability purposes.
----Create testable CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100)) ----INSERT INTO TestTable using SELECT INSERT INTO TestTable (FirstName, LastName) SELECT FirstName, LastName FROM Person.Contact WHERE EmailPromotion = 2 ----Verify that Data in TestTable SELECT FirstName, LastName FROM TestTable ----Clean Up Database DROP TABLE TestTable
For non existing tables - SELECT INTO
You need to use this method when you have not previously created a table, and you need to create it when data from one table is inserted from another into the newly created table. Creates a new table with the same data type as the selected column.
----Create a new table and insert into table using SELECT INSERT SELECT FirstName, LastName INTO TestTable FROM Person.Contact WHERE EmailPromotion = 2 ----Verify that Data in TestTable SELECT FirstName, LastName FROM TestTable ----Clean Up Database DROP TABLE TestTable
If the target table does exist but you do not want to specify a column name:
DECLARE @COLUMN_LIST NVARCHAR(MAX); DECLARE @SQL_INSERT NVARCHAR(MAX); SET @COLUMN_LIST = (SELECT DISTINCT SUBSTRING( ( SELECT ', table1.' + SYSCOL1.name AS [text()] FROM sys.columns SYSCOL1 WHERE SYSCOL1.object_id = SYSCOL2.object_id and SYSCOL1.is_identity <> 1 ORDER BY SYSCOL1.object_id FOR XML PATH ('') ), 2, 1000) FROM sys.columns SYSCOL2 WHERE SYSCOL2.object_id = object_id('dbo.TableOne') ) SET @SQL_INSERT = 'INSERT INTO dbo.TableTwo SELECT ' + @COLUMN_LIST + ' FROM dbo.TableOne table1 WHERE col3 LIKE ' + @search_key EXEC sp_executesql @SQL_INSERT
