An example of the definition of namespaces could be You can use this property to set the default namespace as well. Namespaces are defined in the XML style, as a space-separated list of namespace declaration attributes. Namespaces: Specifies namespaces for use in XPath expressions when it is necessary to define new namespaces externally.

For examples of how to use XPath please refer to (v=vs.110).aspx.

For an explanation of the XPath syntax please refer to.

XPath: This is the expression that states what records to search for. When “Avoid Cache” is on the plugin gets the freshest information. The caching mechanism avoids the plugin to get the updates. This is useful when reading information that changes.

Use Authentication: Allows entering a user name and password In the case the “File Name” is a URI and the remote server requires Basic Authentication.Īvoid Cache: In the case of a remote file, avoid using cache mechanisms that avoid the refresh of data changing in the server side.

These can be read from a remote server or from a local file.įile Name: It can be either the full name of a file or a URI to a remote file to be read. These can be read from a remote server or from a local file. The different types of outputs are exactly as in the case of Excel. Load: It’s a button that invokes the action of reading the data. Key: this is the name of the column in the read query or table from which the keys to the DataTable ought to be taken.įrom row: The row number in the query/table from where to start reading the records. SQL Query: SQL command for querying the database. A good reference on connection strings for several different databases can be found in. Each type of database has a different connection string. In this mode the plugin reads a sheet from a database that supports SQL.Ĭonnection String: The connection string to connect to the database. The separator is by default a pipe character (|), but it can be changed. The output is a string result of the concatenation of all the values. Then the plugin will dump to DataPool the following command: Indexes= In this case, if the parameters are configured as: The following is a typical example of a table in an Excel sheet we would be interested in reading from using DataReader. Load: A button that invokes the action of reading the data. This amount of time is defined in “Automatic Load Period (in seconds)”.Īutomatic Load Period (in seconds): Specifies the period of time between consecutive automatic reads. Load Automatically: Reads the information automatically every certain amount of time. For example, if the prefix is “STV_”, then the plugin will dump the debug information to STV_READER_CONSOLE. Return Variables Prefix: Specifies a prefix to add to the name of the DataPool variables that the plugin uses. This is extremely useful for development and debugging purposes. Show Data: If “on” then it dumps the data the plugin reads to a DataPool variable called READER_CONSOLE.

Post Update Action: Specifies commands (either DataPool or Viz commands) to be executed right after the data is read and sent to the target. Number of rows: The maximum number of records to read, starting from the row stated in “From row”.įields to Read: Specifies by name the columns to read.ĭP Field Name: Specifies the field name in DataPool to where the output will be written.įield is a: Specifies the type of the target. Key: this is the name of the column in the Excel file from which the keys to the DataTable ought to be taken.įrom row: The row number in the Excel sheet from where to start reading the records. Table/Sheet: name of the sheet to be read from within the file. In this mode the plugin reads a sheet from an Excel file. In the case of Shared Memory the plugin creates a character separated string of fields and pushes to the shared memory. In the case of DataPool output types the plugin converts each incoming record to a DataPool command and executes it. All of the different sources of information behave the same way: they all search for records, and translate the records fields to a certain format according to the requested output type.
