SSIS Expression Cheat Sheet


Create a file name with today’s date

Expression on the Flat File or File Connection Manager:

        "C:\\Project\\MyExtract" + (DT_WSTR, 30)(DT_DBDATE)GETDATE() + ".csv"                        

Expression Output Example:

Use a 2 digit date
(ex. “03” for March instead of “3”)

        RIGHT("0" + (DT_WSTR, 2)MONTH(GETDATE()),2)                        

Expression Output:
03 (if the month is March)

Multiple condition if statement

In this example, the statement determines that if the ColumnName is blank or NULL,
it will be set to unknown. To make a Logical AND condition, use “&&” instead of
the “||” operator.

        ISNULL(ColumnName)||TRIM(ColumnName)==""?"Unknown": ColumnName                        
Returns the first five characters from a zip code

Derived Column Transform in the Data Flow:

Remove a given character from a string
(ex. Remove “-” from a social security number)

Derived Column Transform in the Data Flow:

        REPLACE(SocialSecurityNumber, "-","")                        
Uppercase data

Derived Column Transfrom in the Data Flow:

Replace NULL with another value

Derived Column Transform in the Data flow:

        ISNULL(ColumnName)?"New Value" : ColumnName                        
Replace blanks with NULL values

Derived Column Transform in the Data Flow:

        TRIM(ColumnName)=="" ? (DT_STR, 4, 1252)NULL(DT_STR, 4, 1252) : ColumnName
Remove any non-numeric data from a column

Script Transform in the Data Flow Task with the code as follows (VB 2008):

        Imports System.Text.RegularExpressions
        Public Overrides Sub Input()_ProcessInputRows(ByVal Row As Input()Buffer)
             If Row.ColumnName_IsNull = False Or Row.ColumnName = "" Then
                   Dim pattern As String = String.Empty
                   Dim r As Regex = Nothing
                   pattern = "[^0-9]"
                   r = New Regex(pattern, RegexOptions.Compiled)
                   Row.ColumnName = Regex.Replace(Row.ColumnName, pattern, "")
              End If
        End Sub                        
Convert text to proper case
(ex. 1st letter in each word is uppercase)

Script Transform with the line of partial code as follows:

        Row.OutputName = StrConv(Row.InputName, VBStrConv.ProperCase)                       
Build dynamic SQL statement

Expression on the SQLStatementSource property of Execute SQL Task:

        "SELECT Column From " + @[User::TableName] +WHERE
        DateFilterColumn = '" + (DT_WSTR,4)YEAR(@
        [User::DateTimeVar]) + RIGHT("0" + (DT_WSTR,2)MONTH(@
        [User::DateTimeVar]),2) + RIGHT("0" + (DT_WSTR,2)DAY(@
        [User::DateTimeVar]),2) + "'"                        
Round to the nearest two decimal mark

Expression on Derived Column Transform:

        ROUND(YourNumber, 2)
        Expression Output Example: 1.2600000
