Say I have a query like this: Select tbl, BlobAsText(sample) from sqlite_stat4 Where BlobAsText is a UDF that takes a blob and converts it to a string. Now I need to know that the second column of the output needs to be dealt with as text. Is there any SQLite API that can help me with this? sqlite3_column_type and sqlite3_column_decltype can't tell me this information. I could work it out by parsing the SQL or by looking at sqlite3_column_name, but having the UDF name in the column_name doesn't necessarily mean that the output of that column is text. On way to solve this would be to put this information in the field alias, eg: Select tbl, BlobAsText(sample) as BLOB_IS_TEXT from sqlite_stat4, but that is quite restrictive. Any suggestions what the best way is to solve this problem? I do have full control of the application code (the SQLite wrapper).
