.Synopsis
Extract SQL queries from SSIS (dtsx) files.
.DESCRIPTION
Extracts SQL queries from SQL Server Integration services (dtsx) files.
.EXAMPLE
Get-SsisSql -Path MyFile.dtsx
Retrives all SQL queries from the MyFiles.dtsx file.
.EXAMPLE
Get-ChildItem C:\Work\Release -Recurse | Get-SsisSql -Type Lookup, "OLE DB Source" | Where-Object { $_.SQL -like "*SomeTableName*" }
Find all references in LookUps and OLE DB Source components to "SomeTableName" in the SQL.
.OUTPUTS
SsisTools.SsisSql
- FileName = Name of the file
- TaskName = Name of the task in the Control flow
- ComponentName = Name of the component in the Data Flow Task. TaskName for Control flow tasks
- ComponentType = Type of component, e.g "OLE DB Source"
- SQL = The SQL query
