Member Function Documentation

ADODB_sybase::BeginTrans  ) 
 

Begin a Transaction. Must be followed by CommitTrans() or RollbackTrans().

Returns:
true if succeeded or false if database does not support transactions

Reimplemented from ADOConnection.

Definition at line 59 of file adodb-sybase.inc.php.

References ADOConnection::Execute().

Referenced by RowLock().

ADODB_sybase::CommitTrans ok = true  ) 
 

If database does not support transactions, always return true as data always commited

Parameters:
$ok set to false to rollback transaction, true to commit
Returns:
true/false.

Reimplemented from ADOConnection.

Definition at line 69 of file adodb-sybase.inc.php.

References ADOConnection::Execute(), and RollbackTrans().

ADODB_sybase::ErrorMsg  ) 
 

Returns:
the last error message

Reimplemented from ADOConnection.

Reimplemented in ADODB_sybase_ase.

Definition at line 111 of file adodb-sybase.inc.php.

ADODB_sybase::RollbackTrans  ) 
 

If database does not support transactions, rollbacks always fail, so return false

Returns:
true/false.

Reimplemented from ADOConnection.

Definition at line 80 of file adodb-sybase.inc.php.

References ADOConnection::Execute().

Referenced by CommitTrans().

ADODB_sybase::SelectDB dbName  ) 
 

Choose a database to connect to. Many databases do not support this.

Parameters:
dbName is the name of the database to select
Returns:
true or false

Reimplemented from ADOConnection.

Definition at line 97 of file adodb-sybase.inc.php.

Referenced by _connect(), and _pconnect().

& ADODB_sybase::SelectLimit sql,
nrows = -1,
offset = -1,
inputarr = false,
secs2cache = 0
 

Will select, getting rows from $offset (1-based), for $nrows. This simulates the MySQL "select * from table limit $offset,$nrows" , and the PostgreSQL "select * from table limit $nrows offset $offset". Note that MySQL and PostgreSQL parameter ordering is the opposite of the other. eg. SelectLimit('select * from table',3); will return rows 1 to 3 (1-based) SelectLimit('select * from table',3,2); will return rows 3 to 5 (1-based)

Uses SELECT TOP for Microsoft databases (when $this->hasTop is set) BUG: Currently SelectLimit fails with $sql with LIMIT or TOP clause already set

Parameters:
sql 
[offset] is the row to start calculations from (1-based)
[nrows] is the number of rows to get
[inputarr] array of bind variables
[secs2cache] is a private parameter only used by jlim
Returns:
the recordset ($rs->databaseType == 'array')

Reimplemented from ADOConnection.

Definition at line 154 of file adodb-sybase.inc.php.

References ADOConnection::Execute(), and ADOConnection::SelectLimit().

ADODB_sybase::UnixDate v  ) 
 

Also in ADORecordSet.

Parameters:
$v is a date string in YYYY-MM-DD format
Returns:
date in unix timestamp format, or 0 if before TIMESTAMP_FIRST_YEAR, or false if invalid date format

Reimplemented from ADOConnection.

Definition at line 180 of file adodb-sybase.inc.php.

References ADORecordSet_array_sybase::UnixDate().

ADODB_sybase::UnixTimeStamp v  ) 
 

Also in ADORecordSet.

Parameters:
$v is a timestamp string in YYYY-MM-DD HH-NN-SS format
Returns:
date in unix timestamp format, or 0 if before TIMESTAMP_FIRST_YEAR, or false if invalid date format

Reimplemented from ADOConnection.

Definition at line 185 of file adodb-sybase.inc.php.
