Sounds great, it would certainly clean up a lot of my code :) 1: How about sqlite3_prepare_statement() 2: Not really, most of my suggestions will be for virtual table error handling 3: I vote for SQLITE_SCHEMA.
Thanks! -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 07, 2006 8:18 AM To: sqlite-users@sqlite.org Subject: [sqlite] Q about new SQLite API I'm working on a new API routine for SQLite and I have questions for the community. The working name of the new api is sqlite3_prepare_v2(). sqlite3_prepare_v2() works like sqlite3_prepare() in that it generates a prepared statement in an sqlite3_stmt structure. The differences is in the behavior of the resulting sqlite3_stmt and in particular a difference in the way sqlite3_step() responds to the sqlite3_stmt. The differences are these: * You never get an SQLITE_SCHEMA error. sqlite3_prepare_v2 retains the original SQL and automatically reprepares and rebinds it following a schema change. * sqlite3_step() returns the correct error code right away, rather than just returning SQLITE_ERROR and making you call sqlite3_reset() to find the true reason for the error. In this way, I am hoping that sqlite3_prepare_v2() will work around two of the most visible warts in the current API. QUESTION 1: sqlite3_prepare_v2 is the merely the working name for the new function. What should the official name be? Some possibilities include: sqlite3_prepare_ex1 sqlite3_prepare_ng sqlite3_new_prepare sqlite3_compile QUESTION 2: Are there any other API warts that need to be worked around that can be fixed by this same change? QUESTION 3: Suppose there is a schema change and the SQL statement is automatically reprepared. But the schema change is such that the SQL is no longer valid. (Perhaps one of the tables mentioned in a SELECT statement was dropped.) What error code should sqlite3_step() return in that case? -- D.
