Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SQLITE_LIMIT_LENGTH = 0

The maximum size of any string or BLOB or table row, in bytes.

SQLITE_LIMIT_SQL_LENGTH = 1

The maximum length of an SQL statement, in bytes.

SQLITE_LIMIT_COLUMN = 2

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 = 3

The maximum depth of the parse tree on any expression.

SQLITE_LIMIT_COMPOUND_SELECT = 4

The maximum number of terms in a compound SELECT statement.

SQLITE_LIMIT_VDBE_OP = 5

The maximum number of instructions in a virtual machine program used to implement an SQL statement.

SQLITE_LIMIT_FUNCTION_ARG = 6

The maximum number of arguments on a function.

SQLITE_LIMIT_ATTACHED = 7

The maximum number of attached databases.

SQLITE_LIMIT_LIKE_PATTERN_LENGTH = 8

The maximum length of the pattern argument to the LIKE or GLOB operators.

SQLITE_LIMIT_VARIABLE_NUMBER = 9

The maximum index number of any parameter in an SQL statement.

SQLITE_LIMIT_TRIGGER_DEPTH = 10
