Detailed Description

Top-level node for the CREATE [OR REPLACE] SPATIAL REFERENCE SYSTEM statement.

Constructor & Destructor Documentation

PT_create_srs()

PT_create_srs::PT_create_srs ( unsigned long long  srid, const Sql_cmd_srs_attributes &  attributes, bool  or_replace, bool  if_not_exists  )

inline

Member Function Documentation

contains_control_char()

bool PT_create_srs::contains_control_char ( char *  str, size_t  length  )

inlineprivate

Check if a UTF-8 string contains control characters.

Note

This function only checks single byte control characters (U+0000 to U+001F, and U+007F). There are some control characters at U+0080 to U+00A0 that are not detected by this function.

Parameters

str	The string.
length	Length of the string.

Return values

false	The string contains no control characters.
true	The string contains at least one control character.

make_cmd()

Sql_cmd * PT_create_srs::make_cmd ( THD *  thd )

overridevirtual

Implements Parse_tree_root.

Member Data Documentation

m_attributes

const Sql_cmd_srs_attributes PT_create_srs::m_attributes

private

All attributes except SRID.

m_if_not_exists

bool PT_create_srs::m_if_not_exists

private

Whether IF NOT EXISTS is specified.

m_or_replace

bool PT_create_srs::m_or_replace

private

Whether OR REPLACE is specified.

m_srid

unsigned long long PT_create_srs::m_srid

private

SRID of the SRS to create.

The range is larger than that of gis::srid_t, so it must be verified to be less than the uint32 maximum value.

sql_cmd

Sql_cmd_create_srs PT_create_srs::sql_cmd

private

The SQL command object.
