The behavior of certain aspects of the Sybase::DBlib module can be controlled via global or connection specific attributes. To set a global attribute, you would code. Default: set. If set, numeric results are not converted to strings before returning the data to Perl.
Default: unset. See the section on special datatype handling below. The compute id of the current returned row. Is 0 if no compute by clause is currently being processed. The Sybase::Sybperl package is designed for backwards compatibility with sybperl 1.
Its main purpose is to allow sybperl 1. Using this API for new scripts is not recommended, unless portability with older versions of sybperl is essential. Sybase::Sybperl is layered on top of the Sybase::DBlib package, and could therefore suffer a small performance penalty. Establishes a connection to the database engine.
Initializes and allocates resources for the connection, and registers the user name, password, target server, and application name. The attributes hash reference can be used to add private attributes to the connection handle that you can later use, and can also be used to set certain connection properties. This behavior will likely change in the future.
Multiple commands are allowed. Append a command to the current SQL command buffer. Please check the OpenClient documentation for exact usage. This routine returns a results type to indicate the status of returned data. The full list of values is on page of the OpenClient reference manual. Retrieve the column names of the current query. If the current query is not a select statement, then an empty array is returned.
Retrieve the column types of the currently executing query. Retrieves the description of each of the output columns of the current result set. Each element of the returned array is a reference to a hash that describes the column.
This reference points to a static array or hash , so to store the returned rows in an array you must copy the array or hash :. Issue an attention signal to the server about the current transaction. If this call returns TRUE i. Install a callback routine. Returns a reference to the previously installed callback of the specified type, or undef if no callback of that type exists. Retrieves information on the current result set. Initiate a cursor command. Define a command parameter. The following fields are defined: name parameter name , datatype, status, indicator, and value.
Prepare a Dynamic SQL statement. The prepared statement can be called multiple times with different variables, making it quite efficient. Only one active prepared statement can exist per connection. Execute a prepared statement with the specified parameters. This must be called before you can prepare a new statement. This is useful if you need to update TEXT columns in multiple rows by selecting the rows in one connection and doing the update in a different connection. Each row is a reference to an array of scalars.
Memory consumption can therefore become quite important for a query that returns a large number of rows, unless the MaxRows attribute has been set. Send one row to the server. The following routines allow you to make asynchronous calls to the server. The implementation is experimental, and might change in the future, so please use with care.
Before attempting to use this feature you should read the "Asynchronous Programming" chapter in the Sybase OpenClient - Client Library manuals to understand the concepts. In the synchronous mode database requests block until a response is available. In async IO mode the API uses a completion callback to notify the application of pending data for async operations.
Operations will now run in deferred mode, and the perl code will need to be adapted somewhat to handle the async behaviour. As you can see this snippet is quite a bit more complicated than the corresponding synchronous code would be. You can set or retrieve connection properties with this call. In particular you set async mode like this:. Check for completion of an operation. This needs to be called before fetching rows on an async or deferred IO connection. This allocates the appropriate internal buffers for the data columns returned in the query.
So each call to this routine overwrites the data that you just fetched. If you need to save the data you must make a copy of the array. The behavior of certain aspects of the Sybase::CTlib module can be controlled via global or connection specific attributes. This is a no-op. As of sybperl 2. As of release 2.
Using these functions is a little tricky, however. First, it is essential that the TEXT columns appear last in the select statement there can be several TEXT columns in the statement, but they must appear after any regular columns. This operation is a little more complicated. At the moment there is no way to make use of this text pointer directly. Turns the debugging trace on or off. Run the installation package. Accept the default setup options. Install the sybperl module The sybperl module provides Sybase Open Client extensions to perl.
Check that one of the files is named sybperl. Use the perl package manager installed with the perl installation to install the sybperl extensions. From the command line, issue the following command providing the path of wherever you extracted the sybperl files.
Install the dbschema. Extract the files to your directory of choice e. By joining you are opting in to receive e-mail. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Whenever I run "make" I am returned the following errors relating to "CTlib. I am using gcc with cc linking into it. Not sure if this will help, but I had problems installing a module on Sol 8 box.
