Function Documentation

bool get_file_options_ulllist ( const char *&  ptr,
const char *  end,
const char *  line,
uchar *  base,
File_option parameter,
MEM_ROOT *  mem_root 

Parser for FILE_OPTIONS_ULLLIST type value.

[in,out]ptrpointer to parameter
[in]endend of the configuration
[in]linepointer to the line begining
[in]basebase address for parameter writing (structure like TABLE)
[in]mem_rootMEM_ROOT for parameters allocation
const char* parse_escaped_string ( const char *  ptr,
const char *  end,
MEM_ROOT *  mem_root,
LEX_STRING *  str 

parse \n delimited escaped string.

ptrpointer on string beginning
endpointer on symbol after parsed string end (still owned by buffer and can be accessed
mem_rootMEM_ROOT for parameter allocation
strpointer on string, where results should be stored
Return values:
\::pointer on symbol after string
my_bool read_escaped_string ( const char *  ptr,
const char *  eol,
LEX_STRING *  str 

read escaped string from ptr to eol in already allocated str.

ptrpointer on string beginning
eolpointer on character after end of string
strtarget string
Return values:
my_bool rename_in_schema_file ( THD *  thd,
const char *  schema,
const char *  old_name,
const char *  new_db,
const char *  new_name 

Renames a frm file (including backups) in same schema.

thread handler

schemaname of given schema
old_nameoriginal file name
new_dbnew schema
new_namenew file name
Return values:
1Error (only if renaming of frm failed)
my_bool sql_create_definition_file ( const LEX_STRING *  dir,
const LEX_STRING *  file_name,
const LEX_STRING *  type,
uchar *  base,
File_option parameters 

Write new .frm.

dirdirectory where put .frm
file_name.frm file name
type.frm type string (VIEW, TABLE)
basebase address for parameter reading (structure like TABLE)
parametersparameters description
Return values:
File_parser* sql_parse_prepare ( const LEX_STRING *  file_name,
MEM_ROOT *  mem_root,
bool  bad_format_errors 

Prepare frm to parse (read to memory).

file_namepath & filename to .frm file
mem_rootMEM_ROOT for buffer allocation
bad_format_errorssend errors on bad content
returned pointer + 1 will be type of .frm
0 - error
