Cómo usar una función TRIM en SQL Server

Question

No puedo hacer funcionar este código TRIM

SELECT 
   dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], 
   dbo.COL_TBL_VCOURSE.TNG_NA AS [Course Title], 
   LTRIM(RTRIM(FCT_TYP_CD)& '') AND ('' & LTRIM(RTRIM(DEP_TYP_ID) & '')'' AS [Course Owner]

Answer 1

Ejemplo:

DECLARE @Str NVARCHAR(MAX) = N''
            foo   bar
        Foo           Bar        

''

PRINT ''['' + @Str + '']''

DECLARE @StrPrv NVARCHAR(MAX) = N''''

WHILE ((@StrPrv <> @Str) AND (@Str IS NOT NULL)) BEGIN
    SET @StrPrv = @Str

    -- Beginning
    IF EXISTS (SELECT 1 WHERE @Str LIKE ''['' + CHAR(13) + CHAR(10) + CHAR(9) + '']%'')
        SET @Str = LTRIM(RIGHT(@Str, LEN(@Str) - 1))

    -- Ending
    IF EXISTS (SELECT 1 WHERE @Str LIKE ''%['' + CHAR(13) + CHAR(10) + CHAR(9) + '']'')
        SET @Str = RTRIM(LEFT(@Str, LEN(@Str) - 1))
END

PRINT ''['' + @Str + '']''

Resultado

[
            foo   bar
        Foo           Bar        

]
[foo   bar
        Foo           Bar]

Usando fnTrim

SELECT dbo.fnTrim(colName)

Answer 2

Faltan dos paréntesis de cierre ... y no estoy seguro de que un signo funcione como un operador de concatenación de cadenas. Intenta ''+''

SELECT dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], 
dbo.COL_TBL_VCOURSE.TNG_NA AS [Course Title], 
LTRIM(RTRIM(FCT_TYP_CD)) + '') AND ('' + LTRIM(RTRIM(DEP_TYP_ID)) + '')'' AS [Course Owner]

TRIM todos los TAB SPACE y ENTER ''s:

DECLARE @Str VARCHAR(MAX) = ''      
          [         Foo    ]       
          ''

DECLARE @NewStr VARCHAR(MAX) = ''''
DECLARE @WhiteChars VARCHAR(4) =
      CHAR(13) + CHAR(10) -- ENTER
    + CHAR(9) -- TAB
    + '' '' -- SPACE

;WITH Split(Chr, Pos) AS (
    SELECT
          SUBSTRING(@Str, 1, 1) AS Chr
        , 1 AS Pos
    UNION ALL
    SELECT
          SUBSTRING(@Str, Pos, 1) AS Chr
        , Pos + 1 AS Pos
    FROM Split
    WHERE Pos <= LEN(@Str)
)
SELECT @NewStr = @NewStr + Chr
FROM Split
WHERE
    Pos >= (
        SELECT MIN(Pos)
        FROM Split
        WHERE CHARINDEX(Chr, @WhiteChars) = 0
    )
    AND Pos <= (
        SELECT MAX(Pos)
        FROM Split
        WHERE CHARINDEX(Chr, @WhiteChars) = 0
    )

SELECT ''"'' + @NewStr + ''"''

Como funcion

CREATE FUNCTION StrTrim(@Str VARCHAR(MAX)) RETURNS VARCHAR(MAX) BEGIN
    DECLARE @NewStr VARCHAR(MAX) = NULL

    IF (@Str IS NOT NULL) BEGIN
        SET @NewStr = ''''

        DECLARE @WhiteChars VARCHAR(4) =
              CHAR(13) + CHAR(10) -- ENTER
            + CHAR(9) -- TAB
            + '' '' -- SPACE

        IF (@Str LIKE (''%['' + @WhiteChars + '']%'')) BEGIN

            ;WITH Split(Chr, Pos) AS (
                SELECT
                      SUBSTRING(@Str, 1, 1) AS Chr
                    , 1 AS Pos
                UNION ALL
                SELECT
                      SUBSTRING(@Str, Pos, 1) AS Chr
                    , Pos + 1 AS Pos
                FROM Split
                WHERE Pos <= LEN(@Str)
            )
            SELECT @NewStr = @NewStr + Chr
            FROM Split
            WHERE
                Pos >= (
                    SELECT MIN(Pos)
                    FROM Split
                    WHERE CHARINDEX(Chr, @WhiteChars) = 0
                )
                AND Pos <= (
                    SELECT MAX(Pos)
                    FROM Split
                    WHERE CHARINDEX(Chr, @WhiteChars) = 0
                )
        END
    END

    RETURN @NewStr
END

Ejemplo

-- Test
DECLARE @Str VARCHAR(MAX) = ''      
          [         Foo    ]       
              ''

SELECT ''Str'', ''"'' + dbo.StrTrim(@Str) + ''"''
UNION SELECT ''EMPTY'', ''"'' + dbo.StrTrim('''') + ''"''
UNION SELECT ''EMTPY'', ''"'' + dbo.StrTrim(''      '') + ''"''
UNION SELECT ''NULL'', ''"'' + dbo.StrTrim(NULL) + ''"''

Resultado

+-------+----------------+
| Test  | Result         |
+-------+----------------+
| EMPTY | ""             |
| EMTPY | ""             |
| NULL  | NULL           |
| Str   | "[   Foo    ]" |

Answer 4

LTRIM(RTRIM(FCT_TYP_CD)) & '') AND ('' & LTRIM(RTRIM(DEP_TYP_ID)) & '')''

Creo que te estás perdiendo a ) en ambos ajustes. Algunas versiones de SQL solo admiten TRIM, que realiza ajustes L y R ...
