SQLITE_LIMIT_LENGTH(3) FreeBSD Library Functions Manual NAME SQLITE_LIMIT_LENGTH, SQLITE_LIMIT_SQL_LENGTH, SQLITE_LIMIT_COLUMN, SQLITE_LIMIT_EXPR_DEPTH, SQLITE_LIMIT_COMPOUND_SELECT, SQLITE_LIMIT_VDBE_OP, SQLITE_LIMIT_FUNCTION_ARG, SQLITE_LIMIT_ATTACHED, SQLITE_LIMIT_LIKE_PATTERN_LENGTH, SQLITE_LIMIT_VARIABLE_NUMBER, SQLITE_LIMIT_TRIGGER_DEPTH, SQLITE_LIMIT_WORKER_THREADS - Run-Time Limit Categories SYNOPSIS #define SQLITE_LIMIT_LENGTH #define SQLITE_LIMIT_SQL_LENGTH #define SQLITE_LIMIT_COLUMN #define SQLITE_LIMIT_EXPR_DEPTH #define SQLITE_LIMIT_COMPOUND_SELECT #define SQLITE_LIMIT_VDBE_OP #define SQLITE_LIMIT_FUNCTION_ARG #define SQLITE_LIMIT_ATTACHED #define SQLITE_LIMIT_LIKE_PATTERN_LENGTH #define SQLITE_LIMIT_VARIABLE_NUMBER #define SQLITE_LIMIT_TRIGGER_DEPTH #define SQLITE_LIMIT_WORKER_THREADS DESCRIPTION These constants define various performance limits that can be lowered at run-time using sqlite3_limit(). The synopsis of the meanings of the various limits is shown below. Additional information is available at Limits in SQLite. SQLITE_LIMIT_LENGTH The maximum size of any string or BLOB or table row, in bytes. SQLITE_LIMIT_SQL_LENGTH The maximum length of an SQL statement, in bytes. SQLITE_LIMIT_COLUMN The maximum number of columns in a table definition or in the result set of a SELECT or the maximum number of columns in an index or in an ORDER BY or GROUP BY clause. SQLITE_LIMIT_EXPR_DEPTH The maximum depth of the parse tree on any expression. SQLITE_LIMIT_COMPOUND_SELECT The maximum number of terms in a compound SELECT statement. SQLITE_LIMIT_VDBE_OP The maximum number of instructions in a virtual machine program used to implement an SQL statement. If sqlite3_prepare_v2() or the equivalent tries to allocate space for more than this many opcodes in a single prepared statement, an SQLITE_NOMEM error is returned. SQLITE_LIMIT_FUNCTION_ARG The maximum number of arguments on a function. SQLITE_LIMIT_ATTACHED The maximum number of attached databases. SQLITE_LIMIT_LIKE_PATTERN_LENGTH The maximum length of the pattern argument to the LIKE or GLOB operators. SQLITE_LIMIT_VARIABLE_NUMBER The maximum index number of any parameter in an SQL statement. SQLITE_LIMIT_TRIGGER_DEPTH The maximum depth of recursion for triggers. SQLITE_LIMIT_WORKER_THREADS The maximum number of auxiliary worker threads that a single prepared statement may start.
