Ok, I give up. I've been using Whil Hentzen's book "Using SQLite to Bypass The 2GB .DBF Filesize Limit" for a project I'm trying to develop and I have some weird behavior going on.
I'm trying to use SQLite3 to deal with an import file that will have 350+ columns. I've been using the the examples and doing everything via the SQLite3.exe command prompt works as documented. I've also worked out a SQL script using SQLite Expert to drop a table if it exists, create an empty table and the corresponding indexes. Up to this point everything worked as expected.
However, now I'm trying to migrate this code into VFP9 using SQL Pass-Through, but here's what I'm running into:
If I create a DSN using the ODBC drive and then use SQLCONNECT('dsn-name'), the connection is made and if the database file "trnslate.db" doesn't already exist it is created in the folder I designated in the Database Name field of the DSN.
However, if I create DSN-Less connection (SQLSTRINGCONNECT) using the connection string I get back using SQLGETPROP(lnhandle,"ConnectString") , I get a handle, but it is to a "trnslate.db" database that doesn't contain the table I previously created and if the "trnslate.db" table doesn't already exist in the designated folder, it is NOT created on the hard drive. However, it apparently IS created in memory. I can create a table and issue a select command and get back the results I expect, but a database file is NEVER physically created on the hard drive which I need to do for my purposes.
Here is some sample code to see if you can tell me where I'm going wrong:
liH = SQLSTRINGCONNECT( "DRIVER=SQLite3 ODBC Driver;" + ;
"DBNAME=T:\trnslate.db;" + ;
"PWD=;" + ;
"StepAPI=0;" + ;
"SyncPragma=;" + ;
"NoTXN=0;" + ;
"Timeout=;" + ;
"ShortNames=0;" + ;
"LongNames=0;" + ;
"NoCreat=0;" + ;
"NoWCHAR=0;" + ;
"FKSupport=0;" + ;
"JournalMode=;" + ;
"OEMCP=0;" + ;
"BigInt=0;" + ;
"JDConv=0;" + ;
"TraceFile=;")
SQLExec(m.liH, "create table EmplImport (id int primary key, dummy varchar(50));")
SQLExec(m.liH, "insert into EmplImport (id, dummy) values (1,'testing');")
SQLExec(m.liH, "select * from EmplImport;",'dbtest')
SQLDISCONNECT(liH)
I've tried this process about hundred differ ways with different combinations of paired keys in the connection string without success. I've used a DSN-less connection program that I wrote which works perfectly with SQL, MySQL and others and though I never fail to get a handle; the database file never physically exists in any path on the hard drive. Complete searches of my hard drive for the database name yield no results
The code above gives me a value for m.liH which is greater than zero, I never get errors thrown, I always get a valid handle, the table can be created, the data inserted and I get a cursor back from the select named 'dbtest' with the exact data inserted on the previous line.
I've been on this for about six hours and I'm no closer to making this work as a DSN-less project even though Whil seemed to imply in the book that this was his preferred method of doing things.
HELP!
