Error received when importing using delimited text, if string quote character is left blank:
"Index was outside the bounds of the array"
You should use a single quote for the quote character even though the data file doesn't contain quotes for the character fields.
Toad for SQL Server import wizard requires that the "String Quote Character" for a delimited data file be specified. Specify a single quote will do the trick even thought the data file doesn't have the quotes for the character fields.
Applies to all versions of Toad for SQL Server.
