| SelectLimit($sql,$nrows=-1,$offset=-1, $inputarr=false,$secs2cache=0) X-Ref |
| 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 $sql with LIMIT or TOP clause already set param: sql param: [offset] is the row to start calculations from (1-based) param: [nrows] is the number of rows to get param: [inputarr] array of bind variables param: [secs2cache] is a private parameter only used by jlim return: the recordset ($rs->databaseType == 'array') |

| No description |
| Replace($table, $fieldArray, $keyCol, $autoQuote=false, $has_autoinc=false) X-Ref |
| Insert or replace a single record. Note: this is not the same as MySQL's replace. ADOdb's Replace() uses update-insert semantics, not insert-delete-duplicates of MySQL. Also note that no table locking is done currently, so it is possible that the record be inserted twice by two programs... $this->Replace('products', array('prodname' =>"'Nails'","price" => 3.99), 'prodname'); $table table name $fieldArray associative array of data (you must quote strings yourself). $keyCol the primary key field name or if compound key, array of field names autoQuote set to true to use a hueristic to quote strings. Works with nulls and numbers but does not work with dates nor SQL functions. has_autoinc the primary key is an auto-inc field, so skip in insert. Currently blob replace not supported returns 0 = fail, 1 = update, 2 = insert |
| CacheSelectLimit($secs2cache,$sql,$nrows=-1,$offset=-1,$inputarr=false) X-Ref |
| 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. CacheSelectLimit(15,'select * from table',3); will return rows 1 to 3 (1-based) CacheSelectLimit(15,'select * from table',3,2); will return rows 3 to 5 (1-based) BUG: Currently CacheSelectLimit fails with $sql with LIMIT or TOP clause already set param: [secs2cache] seconds to cache data, set to 0 to force query. This is optional param: sql param: [offset] is the row to start calculations from (1-based) param: [nrows] is the number of rows to get param: [inputarr] array of bind variables return: the recordset ($rs->databaseType == 'array') |
| CacheFlush($sql=false,$inputarr=false) X-Ref |
| Flush cached recordsets that match a particular $sql statement. If $sql == false, then we purge all files in the cache. |
| _gencachename($sql,$createdir) X-Ref |
| Private function to generate filename for caching. Filename is generated based on: - sql statement - database type (oci8, ibase, ifx, etc) - database name - userid - setFetchMode (adodb 4.23) When not in safe mode, we create 256 sub-directories in the cache directory ($ADODB_CACHE_DIR). Assuming that we can have 50,000 files per directory with good performance, then we can scale to 12.8 million unique cached recordsets. Wow! |
| CacheExecute($secs2cache,$sql=false,$inputarr=false) X-Ref |
| Execute SQL, caching recordsets. param: [secs2cache] seconds to cache data, set to 0 to force query. param: sql SQL statement to execute param: [inputarr] holds the input data to bind to return: RecordSet or false |

| No description |
| GetUpdateSQL(&$rs, $arrFields,$forceUpdate=false,$magicq=false,$force=null) X-Ref |
| Generates an Update Query based on an existing recordset. $arrFields is an associative array of fields with the value that should be assigned. Note: This function should only be used on a recordset that is run against a single table and sql should only be a simple select stmt with no groupby/orderby/limit "Jonathan Younger" <jyounger@unilab.com> |
| GetInsertSQL(&$rs, $arrFields,$magicq=false,$force=null) X-Ref |
| Generates an Insert Query based on an existing recordset. $arrFields is an associative array of fields with the value that should be assigned. Note: This function should only be used on a recordset that is run against a single table. |
| UpdateBlob($table,$column,$val,$where,$blobtype='BLOB') X-Ref |
| Update a blob column, given a where clause. There are more sophisticated blob handling functions that we could have implemented, but all require a very complex API. Instead we have chosen something that is extremely simple to understand and use. Note: $blobtype supports 'BLOB' and 'CLOB', default is BLOB of course. Usage to update a $blobvalue which has a primary key blob_id=1 into a field blobtable.blobcolumn: UpdateBlob('blobtable', 'blobcolumn', $blobvalue, 'blob_id=1'); Insert example: $conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)'); $conn->UpdateBlob('blobtable','blobcol',$blob,'id=1'); |
| UpdateBlobFile($table,$column,$path,$where,$blobtype='BLOB') X-Ref |

Class: ADODB_Iterator - X-Ref
Class: ADORecordSet - X-Ref
RecordSet class that represents the dataset returned by the database.To keep memory overhead low, this class holds only the current row in memory.
No prefetching of data is done, so the RecordCount() can return -1 ( which
means recordcount not known).
