[sqlite] Pragma integrity_check

Hi, I have few questions regarding "Pragma integrity_check" 1. I have test table: PRAGMA ignore_check_constraints = true; CREATE TABLE dtest1(the_key INTEGER NOT NULL, versionId INTEGER , primary key (the_key), check( versionId <> 0 ) ) WITHOUT ROWID INSERT into dtest1 values (0,0); PRA

Dear SQLiters, PRAGMA integrity_check is described to check UNIQUE and NOT NULL constraints. Does it check other CHECK constraints specified in the column definition? Thank you, Roman

Hi, I have SQLite 2.x database and sometimes it takes a long time to run "integrity_check" on the database. Looking at the integrity_check option "(integer), we could control how many errors to return from the check. I tried the option, but it generated a syntax error. Is the option supported?

From the manual: PRAGMA integrity_check: The command does an integrity check of the entire database. It looks for out-of-order records, missing pages, malformed records, and corrupt indices. If any problems are found, then a single string is returned which is a description of all problems.
