SSIS Expressions Cheat Sheet

Problem Expression
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 on the Flat File or File Connection Manager:
"C:\\Project\\MyExtract" + (DT_WSTR, 30)(DT_DBDATE)GETDATE() + ".csv"
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
