Member Function Documentation

ADOConnection::_dirFlush dir,
kill_top_level = false
 

Private function to erase all of the files and subdirectories in a directory.

Just specify the directory, and tell it if you want to delete the directory or just clear it out. Note: $kill_top_level is used internally in the function to flush subdirectories.

Definition at line 1546 of file adodb.inc.php.

ADOConnection::_gencachename sql,
createdir
 

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!

Definition at line 1606 of file adodb.inc.php.

& ADOConnection::_rs2rs &$  rs,
nrows = -1,
offset = -1,
close = true
 

Convert database recordset to an array recordset input recordset's cursor should be at beginning, and old $rs will be closed.

Parameters:
rs the recordset to copy
[nrows] number of rows to retrieve (optional)
[offset] offset by number of rows (optional)
Returns:
the new recordset

ADOConnection::addq s,
magic_quotes = false
 

Quotes a string, without prefixing nor appending quotes.

Definition at line 2388 of file adodb.inc.php.

ADOConnection::Affected_Rows  ) 
 

Returns:
# rows affected by UPDATE/DELETE

Definition at line 995 of file adodb.inc.php.

ADOConnection::BeginTrans  ) 
 

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

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

Reimplemented in ADODB_access, ADODB_ado, ADODB_ado, ADODB_ado_access, ADODB_borland_ibase, ADODB_db2, ADODB_ibase, ADODB_mysql, ADODB_mysqlt, ADODB_oci8, ADODB_odbc, ADODB_odbtp, ADODB_oracle, ADODB_pdo, ADODB_postgres64, ADODB_sqlite, ADODB_sybase, and ADODB_vfp.

& ADOConnection::CacheExecute secs2cache,
sql = false,
inputarr = false
 

Execute SQL, caching recordsets.

Parameters:
[secs2cache] seconds to cache data, set to 0 to force query. This is an optional parameter.
sql SQL statement to execute
[inputarr] holds the input data to bind to
Returns:
RecordSet or false

ADOConnection::CacheFlush sql = false,
inputarr = false
 

Flush cached recordsets that match a particular $sql statement. If $sql == false, then we purge all files in the cache.

Definition at line 1512 of file adodb.inc.php.

References outp().

& ADOConnection::CachePageExecute secs2cache,
sql,
nrows,
page,
inputarr = false
 

Will select the supplied $page number from a recordset, given that it is paginated in pages of $nrows rows per page. It also saves two boolean values saying if the given page is the first and/or last one of the recordset. Added by Iván Oliva to provide recordset pagination.

Parameters:
secs2cache seconds to cache data, set to 0 to force query
sql 
nrows is the number of rows per page to get
page is the page number to get (1-based)
[inputarr] array of bind variables
Returns:
the recordset ($rs->databaseType == 'array')

Definition at line 2485 of file adodb.inc.php.

& ADOConnection::CacheSelectLimit secs2cache,
sql,
nrows = -1,
offset = -1,
inputarr = false
 

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

Parameters:
[secs2cache] seconds to cache data, set to 0 to force query. This is optional
sql 
[offset] is the row to start calculations from (1-based)
[nrows] is the number of rows to get
[inputarr] array of bind variables
Returns:
the recordset ($rs->databaseType == 'array')

Will select the supplied $page number from a recordset, given that it is paginated in pages of $nrows rows per page. It also saves two boolean values saying if the given page is the first and/or last one of the recordset. Added by Iván Oliva to provide recordset pagination.

See readme.htm::ex8 for an example of usage.

Parameters:

nrows is the number of rows per page to get
page is the page number to get (1-based)
[inputarr] array of bind variables
[secs2cache] is a private parameter only used by jlim
Returns:

Should prepare the sql statement and return the stmt resource. For databases that do not support this, we return the $sql. To ensure compatibility with databases that do not support prepare:

Parameters:
sql SQL to send to database
Returns:
return FALSE, or the prepared statement, or the original sql if if the database does not support prepare.

ADOConnection::qstr s,

Correctly quotes a string so that all strings are escaped. We prefix and append to the string single-quotes. An example is $db->qstr("Don't bother",magic_quotes_runtime());

Parameters:
s the string to quote
[magic_quotes] if $s is GET/POST var, set to get_magic_quotes_gpc(). This undoes the stupidity of magic quotes for GPC.

ADOConnection::Replace table,
fieldArray,
keyCol,
autoQuote = false,
has_autoinc = false
 

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

& ADOConnection::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

Improved method of initiating a transaction. Used together with CompleteTrans(). Advantages include:

b. CompleteTrans auto-detects SQL errors, and will rollback on errors, commit otherwise.
c. All BeginTrans/CommitTrans/RollbackTrans inside a StartTrans/CompleteTrans block are disabled, making it backward compatible.

ADOConnection::UpdateBlob table,

val,
where,
blobtype = 'BLOB'
 

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');
