I have data like this:
string 1: 003Preliminary Examination Plan
string 2: Coordination005
string 3: Balance1000sheet
The output I expect is
string 1: 003
string 2: 005
string 3: 1000
And I want to implement it in SQL.
First create this UDF
CREATE FUNCTION dbo.udf_GetNumeric
(
@strAlphaNumeric VARCHAR(256)
)
RETURNS VARCHAR(256)
AS
BEGIN
DECLARE @intAlpha INT
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric)
BEGIN
WHILE @intAlpha > 0
BEGIN
SET @strAlphaNumeric = STUFF(@strAlphaNumeric, @intAlpha, 1, '' )
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric )
END
END
RETURN LEN(COALESCE(TRIM(CAST(ISNULL(@strAlphaNumeric, 0) AS INT)),0))>0 then COALESCE(TRIM(CAST(ISNULL(@strAlphaNumeric, 0) AS INT)),0) else 0 end
END
GO
Now use the function
as
SELECT dbo.udf_GetNumeric(column_name)
from table_name
I hope this solved your problem.
