Member Function Documentation

◆ _appendN()

ADODB_mssql_n::_appendN ( $inboundData )

This function will intercept all the literals used in the SQL, prepending the "N" char to them in order to allow mssql to store properly data sent in the correct UCS-2 encoding (by freeTDS and ODBTP) keeping SQL compatibility at ADOdb level (instead of hacking every project to add the "N" notation when working against MSSQL.

The original note indicated that this hack should only be used if ALL the char-based columns in your DB are of type nchar, nvarchar and ntext, but testing seems to indicate that SQL server doesn't seem to care if the statement is used against char etc fields.

Todo: This function should raise an ADOdb error if one of the transformations fail

Parameters

mixed $inboundData Either a string containing an SQL statement or an array with resources from prepared statements

Return values

mixed

◆ _CreateCache()

ADOConnection::_CreateCache ( )

mixed[]|bool

◆ CachePageExecute()

ADOConnection::CachePageExecute	(	$secs2cache,
		$sql,
		$nrows,
		$page,
		$inputarr = false )

inherited

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

int	$secs2cache	seconds to cache data, set to 0 to force query
string	$sql
int	$nrows	is the number of rows per page to get
int	$page	is the page number to get (1-based)

inherited

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

int	$secs2cache	Seconds to cache data, set to 0 to force query. This is optional
string	$sql
int	$offset	Row to start calculations from (1-based)
int	$nrows	Number of rows to get

◆ Replace()

ADOConnection::Replace	(	$table,
		$fieldArray,
		$keyCol,
		$autoQuote = false,
		$has_autoinc = false )

inherited

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 heuristic 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

◆ resetLastError()

inherited

Select a limited number of rows.

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

a. StartTrans/CompleteTrans is nestable, unlike BeginTrans/CommitTrans/RollbackTrans. Only the outermost block is treated as a transaction.
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.

◆ substr()

ADODB_mssql::substr	(	$fld,
		$start,
		$length = 0 )

inherited

Returns a substring of a varchar type field.

The SQL server version varies because the length is mandatory, so we append a reasonable string length

Parameters

string	$fld	The field to sub-string
int	$start	The start point
int	$length	An optional length

Return values

The SQL text

Reimplemented from ADOConnection.

◆ textMax()

ADOConnection::textMax ( )

inherited

Returns the maximum size of a MetaType X field.

If the method is not defined in the driver returns ADODB_STRINGMAX_NOTSET

Return values

int

Reimplemented in ADODB_mssqlnative, ADODB_odbc_mssql, and ADODB_sqlite.

◆ Time()

ADOConnection::Time ( )

inherited

Return the database server's current date and time.

int|false

Reimplemented in ADODB_oci8, and ADODB_pdo.

◆ UnixDate()

static ADOConnection::UnixDate ( $v )

staticinherited

Also in ADORecordSet.

Parameters

mixed $v is a date string in YYYY-MM-DD format

Return values

int|false Date in unix timestamp format, or 0 if before TIMESTAMP_FIRST_YEAR, or false if invalid date format

Reimplemented in ADODB_sybase.

◆ UnixTimeStamp()

static ADOConnection::UnixTimeStamp ( $v )

staticinherited

Also in ADORecordSet.

Parameters

string | object $v is a timestamp string in YYYY-MM-DD HH-NN-SS format

◆ updateBlob()

ADOConnection::updateBlob	(	$table,
		$column,
		$val,
		$where,
		$blobtype = 'BLOB' )

inherited

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.

Sample usage:

update a BLOB in field table.blob_col with value $blobValue, for a record having primary key id=1 $conn->updateBlob('table', 'blob_col', $blobValue, 'id=1');
insert example: $conn->execute('INSERT INTO table (id, blob_col) VALUES (1, null)'); $conn->updateBlob('table', 'blob_col', $blobValue, 'id=1');

Parameters

string	$table
string	$column
string	$val	Filename containing blob data
mixed	$where	{

See also: updateBlob()}

Parameters

string $blobtype supports 'BLOB' (default) and 'CLOB'

Return values

bool success

Reimplemented in ADODB_db2.

◆ updateBlobFile()

ADOConnection::updateBlobFile	(	$table,
		$column,
		$path,
		$where,
		$blobtype = 'BLOB' )

inherited

Update a BLOB from a file.

Usage example: $conn->updateBlobFile('table', 'blob_col', '/path/to/file', 'id=1');

Parameters

string	$table
string	$column
string	$path	Filename containing blob data
mixed	$where	{

See also: updateBlob()}

Parameters

string $blobtype supports 'BLOB' and 'CLOB'

Return values

bool success

◆ UpdateClob()

ADOConnection::UpdateClob	(	$table,
		$column,
		$val,
		$where )

inherited

Usage: UpdateClob('TABLE', 'COLUMN', $var, 'ID=1', 'CLOB');.

$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, null)'); $conn->UpdateClob('clobtable','clobcol',$clob,'id=1');

◆ UserDate()

ADOConnection::UserDate	(	$v,
		$fmt = 'Y-m-d',
		$gmt = false )

◆ $_errorCode

int false ADOConnection::$_errorCode = false

inherited

Stores the last returned error code.

Not guaranteed to be used. Only some drivers actually populate it.

◆ $_errorMsg

string false ADOConnection::$_errorMsg = false

inherited

Stores the last returned error message.

See also: ADOConnection\errorMsg()

◆ $connectionParameters

array ADOConnection::$connectionParameters = array()

protectedinherited

Additional parameters that may be passed to drivers in the connect string.

Data is stored as an array of arrays and not a simple associative array, because some drivers (e.g. mysql) allow multiple parameters with the same key to be set. @externalurl https://github.com/ADOdb/ADOdb/issues/187

See also: setConnectionParameter()

$connectionParameters Set of ParameterName => Value pairs

◆ $database

string ADOConnection::$database = ''

inherited

RDBMS currently in use, eg. odbc, mysql, mssql.

Current database name.

This used to be stored in the $databaseName property, which was marked as deprecated in 4.66 and removed in 5.22.5.

◆ $dsnType

string ADOConnection::$dsnType = ''

inherited

If the driver is PDO, then the dsnType is e.g.

sqlsrv, otherwise empty

◆ $evalAll

string ADOConnection::$evalAll = false

inherited

set to true if ADOConnection.Execute() permits binding of array parameters.

Eval string used to filter data. Only used in the deprecated Text driver.
