Problem: This is just a case of a two part setting being in two oddly different places. A column is set to TextQualified under Connection Manager Editor, Advanced, Column Name, TextQualified (true). The Text Qualifier itself is set under The file connection's properties.
Solution: In addition to enabling the TextQualified setting at a column level. The qualifier has to be specified at the connection properties level.
To set the Text Qualifier:
- In SQL Server Data Tools.
- Right click the Connection Manager and select Properties
- In the Properties pane on the right hand side, under Misc
- Enter your Text Qualifier (e.g. ") in the TextQualifier property.
