This is code I used a while ago. Don't use it anymore as I have a better
way to do this via my VB wrapper. There are some lines that deal with code
in other parts of my application, but I take it you can see that.
In case you didn't know this is VB(A).
Function GetSQLiteTableInfo2(strDB As String, _
strTable As String, _
Optional strSelect As String, _
Optional strOmitFields As String, _
Optional strAlias As String, _
Optional strFields As String, _
Optional strDataTypes As String, _
Optional bCurrentConnection As Boolean) As
String()
'will produce the table fields as an 0-based 1-D array
'and make the strings:
'field1,field2,field3 etc.
'field1, field2, field3 etc.
'datatype1,datatype2,datatype3 etc.

Subject: [sqlite] Helping with table definition?
Hello,
Merry Christmas for every one!
I am wondering if someone did a function (the language doesn't care very
much) to get the table information and want to share him/her code.
I know that you can have the SQL definition of a table doing a "select *
from sqlite_master where type='table' ", but I need to parse SQL and
understand it.
Thanks in advance.
