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 

Member Function Documentation

◆ contains_control_char()

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

Check if a UTF-8 string contains control characters.

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.
strThe string.
lengthLength of the string.
Return values
falseThe string contains no control characters.
trueThe string contains at least one control character.

◆ make_cmd()

Sql_cmd* PT_create_srs::make_cmd ( THD thd)

Implements Parse_tree_root.

Member Data Documentation

◆ m_attributes

const Sql_cmd_srs_attributes PT_create_srs::m_attributes

All attributes except SRID.

◆ m_if_not_exists

bool PT_create_srs::m_if_not_exists

Whether IF NOT EXISTS is specified.

◆ m_or_replace

bool PT_create_srs::m_or_replace

Whether OR REPLACE is specified.

◆ m_srid

unsigned long long PT_create_srs::m_srid

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

The SQL command object.
