13 May 2002 DBGetRecordSet()
AuthorJens Meyer (sealeopard@usa.net)
Action Retrives a recordset from a database as the result of a SQL query.
SyntaxDBGetRecordSet (connection, SQL [,cmdType, curType, lockType]) 
Parameters
  • connection (Required / String) open connection object to a data source
  • SQL (Required / String) SQL query to be executed
  • cmdType (Optional / Numeric) optional integer value denoting the command type
  • curType (Optional / Numeric) optional integer value denoting the cursor type
  • lockType (Optional / Numeric) optional integer value denoting the lock type 
  • RemarksKixtart cannot handle two-dimensional arrays without third-party UDFs. Thus, the returned recordset is an array of records. Each record consists of a CHR(10)-delimited string of the recordset fields. This use of delimiters implies that the recordset field values cannot contain the CHR(10) character. If values can potentialy contain a CHR(10) character (like a BLOB) then this function must not be used. Instead, you can manually retrieve values after using DBRecordsetOpen().

    ReturnsArray of records with CHR(10)-delimited fields or an empty string if the SQL query results in an empty recordset. 
    DependenciesNone. 
    Examples
    $objConn = DBConnOpen('DRIVER={Microsoft Access Driver (*.mdb)}; UID=; PWD=; DBQ=database.mdb')
    $recordset = DBGetRecordset($objConn,"SELECT Field1, Field2 FROM Demo WHERE Field1<>'' ORDER BY Field1")
    $retcode = DBConnClose($objConn)
    for each $record in $recordset
      $recordsetfields=split($record,chr(10))
