Function Documentation

TDS_SERVER_TYPE odbc_c_to_server_type ( int  c_type)

Pass this an SQL_C_* type and get a SYB* type which most closely corresponds to the SQL_C_* type.

This function can return XSYBNVARCHAR or SYBUINTx even if server do not support it

Here is the caller graph for this function:

SQLRETURN odbc_set_concise_c_type ( SQLSMALLINT  concise_type,
struct _drecord drec,
int  check_only 
)

Set concise type and all cascading field.

Parameters
concise_typeconcise type to set
drecrecord to set. NULL to test error without setting
check_onlyit <>0 (true) check only, do not set type
SQLRETURN odbc_set_concise_sql_type ( SQLSMALLINT  concise_type,
struct _drecord drec,
int  check_only 
)

Set concise type and all cascading field.

Parameters
concise_typeconcise type to set
drecrecord to set. NULL to test error without setting
check_onlyit <>0 (true) check only, do not set type
SQLRETURN odbc_set_string_flag ( TDS_DBC dbc,
SQLPOINTER  buffer,
SQLINTEGER  cbBuffer,
void FAR *  pcbBuffer,
const char *  s,
int  len,
int  flag 
)

Copy a string to client setting size according to ODBC convenction.

Parameters
dbcdatabase connection. Can be NULL
bufferclient buffer
cbBufferclient buffer size (in bytes)
pcbBufferpointer to SQLSMALLINT to hold string size
sstring to copy
lenlen of string to copy. <0 null terminated
flagset of flag 0x10 SQLINTEGER
