How to insert the results from mulitiple unions into a single table

  • Hello,

    I've created a multiple unions between 4 tables to combines the results of these select statement. Can someone tell me the syntax/or example of how to insert the results from the union into a new table. I've looked on the internet and some of the syntax used does not seem to work.

    Here is my attempt so far

    CREATE TABLE mytable (ItemNumber nvarchar(50),

    SalesRegionLevel4Code nvarchar(50),

    SalesRegionLevel4Description nvarchar(50),

    CustomerTypeLevel1Code nvarchar(50),

    CustomerTypeLevel2Description nvarchar(50),

    RowRecordedDateTime datetime,

    Name nvarchar(50))

    GO

    INSERT INTO mytable

    SELECT T.ItemNumber

    , T.SalesRegionLevel4Code

    , T.SalesRegionLevel4Description

    , T.CustomerTypeLevel1Code

    , T.CustomerTypeLevel2Description

    , T.RowRecordedDateTime

    , CASE T.Name when 'Null'

    THEN ''

    ELSE '1'

    END AS Name

    FROM TEMP1 T

    union all

    SELECT T2.ItemNumber

    , T2.SalesRegionLevel4Code

    , T2.SalesRegionLevel4Description

    , T2.CustomerTypeLevel1Code

    , T2.CustomerTypeLevel2Description

    , T2.RowRecordedDateTime

    , CASE T2.Name when 'Null'

    THEN ''

    ELSE '2'

    END AS Name

    FROM TEMP2 T2

    union all

    SELECT T3.ItemNumber

    , T3.SalesRegionLevel4Code

    , T3.SalesRegionLevel4Description

    , T3.CustomerTypeLevel1Code

    , T3.CustomerTypeLevel2Description

    , T3.RowRecordedDateTime

    , CASE T3.Name when 'Null'

    THEN ''

    ELSE '3'

    END AS Name

    FROM TEMP3 T3

    union all

    SELECT T4.ItemNumber

    , T4.SalesRegionLevel4Code

    , T4.SalesRegionLevel4Description

    , T4.CustomerTypeLevel1Code

    , T4.CustomerTypeLevel2Description

    , T4.RowRecordedDateTime

    , CASE T4.Name when 'Null'

    THEN ''

    ELSE '4'

    END AS Name

    FROM TEMP4 T4

    Thanks in advance

    Steve

    Please will you be a bit more specific. Error messages? Unexpected results?

    Thanks

  • Hi John

    Thanks for your reply I've managed to get it working now. The error i got before were invalid object and syntax near ')' in my older version i was missing a bracket which i have now included.

    CREATE TABLE Test(ItemNumber nvarchar(50),

    SalesRegionLevel4Code nvarchar(50),

    SalesRegionLevel4Description nvarchar(50),

    CustomerTypeLevel1Code nvarchar(50),

    CustomerTypeLevel2Description nvarchar(50),

    RowRecordedDateTime datetime,

    Name nvarchar(50)) -- originally missing a bracket in my older version

    GO

    INSERT INTO Test

    SELECT T.ItemNumber

    , T.SalesRegionLevel4Code

    , T.SalesRegionLevel4Description

    , T.CustomerTypeLevel1Code

    , T.CustomerTypeLevel2Description

    , T.RowRecordedDateTime

    , CASE T.Name when 'Null'

    THEN ''

    ELSE '1'

    END AS Name

    FROM TEMP1 T

    union all

    SELECT T2.ItemNumber

    , T2.SalesRegionLevel4Code

    , T2.SalesRegionLevel4Description

    , T2.CustomerTypeLevel1Code

    , T2.CustomerTypeLevel2Description

    , T2.RowRecordedDateTime

    , CASE T2.Name when 'Null'

    THEN ''

    ELSE '2'

    END AS Name

    FROM TEMP2 T2

    union all

    SELECT T3.ItemNumber

    , T3.SalesRegionLevel4Code

    , T3.SalesRegionLevel4Description

    , T3.CustomerTypeLevel1Code

    , T3.CustomerTypeLevel2Description

    , T3.RowRecordedDateTime

    , CASE T3.Name when 'Null'

    THEN ''

    ELSE '3'

    END AS Name

    FROM TEMP3 T3

    union all

    SELECT T4.ItemNumber

    , T4.SalesRegionLevel4Code

    , T4.SalesRegionLevel4Description

    , T4.CustomerTypeLevel1Code

    , T4.CustomerTypeLevel2Description

    , T4.RowRecordedDateTime

    , CASE T4.Name when 'Null'

    THEN ''

    ELSE '4'

    END AS Name

    FROM TEMP4 T4
