Function Documentation

◆ add_system_variable_assignment()

static bool add_system_variable_assignment	(	THD *	thd,
		LEX_CSTRING	prefix,
		LEX_CSTRING	suffix,
		enum enum_var_type	var_type,
		Item *	val
	)

static

Helper action for a SET statement.

Used to push a system variable into the assignment list. In stored routines detects "SET AUTOCOMMIT" and reject "SET GTID..." stuff.

Parameters

thd	the current thread
prefix	left hand side of a qualified name (if any) or nullptr string
suffix	the right hand side of a qualified name (if any) or a whole unqualified name
var_type	the scope of the variable
val	the value being assigned to the variable

Returns: true if error, false otherwise.

◆ check_unsupported_json_table_default()

static bool check_unsupported_json_table_default ( const Item * item )

static

◆ find_sp_variable()

static sp_variable * find_sp_variable	(	const Parse_context &	pc,
		const LEX_CSTRING &	name
	)

static

Try to resolve a name as SP formal parameter or local variable.

Note: Doesn't output error messages on failure.

Parameters

pc	Parse context
name	Name of probable SP variable

Returns: pointer to SP formal parameter/local variable object on success, otherwise nullptr

◆ init_alter_table_stmt()

static bool init_alter_table_stmt	(	Table_ddl_parse_context *	pc,
		Table_ident *	table_name,
		Alter_info::enum_alter_table_algorithm	algo,
		Alter_info::enum_alter_table_lock	lock,
		Alter_info::enum_with_validation	validation
	)

static

A common initialization part of ALTER TABLE statement variants.

Parameters

pc	The parse context.
table_name	The name of a table to alter.
algo	The ALGORITHM clause: inplace, copy etc.
lock	The LOCK clause: none, shared, exclusive etc.
validation	The WITH or WITHOUT VALIDATION clause.

Returns: false on success, true on error.

◆ is_any_transition_variable_prefix()

static bool is_any_transition_variable_prefix	(	const Parse_context &	pc,

Parameters

pc	Parse context
opt_prefix	Optional prefix to examine or empty LEX_CSTRING
prefix	"OLD" or "NEW" to compare with

Returns: true if the OLD transition variable syntax, otherwise false
