Via Menu “File” -> “Create CSV Text connection” you can create this connection type in Server Manager and query the CSV Files like a simple tables.

This is done with the CsvDriver. The SQL Syntax is limited by the driver and is executed localy. You can’t use the Caché SQL Syntax cause it is not Caché you’re using.

Some short details:

• CsvJdbc accepts all types of CSV files defined by RFC 4180.
• CsvJdbc accepts only SQL SELECT queries from a single table and does not support INSERT, UPDATE, DELETE or CREATE statements.
• SQL sub-queries are permitted but joins between tables in SQL SELECT queries are not yet supported.
• SQL SELECT queries must be of the following format:
  
SELECT [DISTINCT] [table-alias.]column [[AS] alias], ...
FROM table [[AS] table-alias]
WHERE [NOT] condition [AND | OR condition] ...
GROUP BY column ... [HAVING condition ...]
ORDER BY column [ASC | DESC] ...
LIMIT n [OFFSET n]

Using ZIP Files

You can pick up a ZIP file that contains multible csv text files.

Please see the next Screenshot for details. The CSV Connection is created to the file “IDS_CSV.zip”. That that coctain multible files one of them ist called “IDS_DATA.csv”. By opening a query editor and writing the query “SELECT * FROM IDS_Data” you can view and analyse this text file:

Using folder with many csv files without importing!

You can just select a Folder for a CSV Connection and automatically query all *.csv files within this folder via SQL. Please see the next Screenshot for details. The CSV Connection is created for a folder called “testdata” within this folder exists a file called “population.csv”. Just write “select * from population LIMIT 100” to get the first 100 rows of this file.

to the Connection Properties dialog in Caché Monitor:

1. Host \ IP Address
   Specifies the IP address in dotted decimal such as “127.0.0.1” or just the server name

2. Host Port Number
   Specifies the port for connecting to the DSN. The default for Caché is 1972.

3. User Name
   Specifies the username for logging into the DSN. By default, this is “_SYSTEM” and is not case sensitive.

4. Password
   Specifies the password for the account specified by the UID entry. For the SYSTEM username, the password is “SYS” and is case sensitive.

5. Caché Namespace
   Specifies the namespace for the DSN. For Caché Monitor this information is not required cause Caché Monitor shows all Namespaces from Server for easy navigation. A User Name with the enough rights to query this information from SYS database is required. If the selected User hasen’t the required rights, on the Details tab a namespace can be selected (entered).

There are two configuration options enabled by default to let Caché Monitor work better with network proxies. Please disable these options and try again.

To do that open the config.properties file (you find it in the Caché Monitor install folder) and change two lines from:

system.java.net.useSystemProxies=true
system.java.net.preferIPv4Stack=true

into this

#system.java.net.useSystemProxies=true
#system.java.net.preferIPv4Stack=true

Alternatively you can also remove the lines

After doing this restart Caché Monitor please. Now the error message should be gone.

The Query Cloud is like a virtual database. Within this virtual database you can query and use data from different databases, combine them with SQL as if they are in the same database. The jTDS database driver is an free driver for Microsoft SQL Server (6.5, 7, 2000, 2005, 2008 and 2012) and Sybase Adaptive Server Enterprise (10, 11, 12 and 15). Read this to get details about register the jTDS driver within Caché Monitor.

If you want to add a table to Caché Monitors Query Cloud to combine them with other tables (data) from another datasources there exists a limitation that need to be respected: To adding tables from a jTDS datasource to the Query Cloud we recommed to create a seperate connection within Caché Monitor for the source database.

For example: If you want to add tables from the AdvatureWorks2014 database, the connection information (connection url) should contain the database:

In the Server Navigator you can view tables from any database on the specific server. But only tables from the database that are specified in the connection url e.g. AdventureWorks2014 should be added to the Query Cloud!

The post How to use the jTDS database driver with Caché Monitors – Query Cloud appeared first on Tools for InterSystems Caché and Intersystems IRIS.

This database driver is an open source driver for MS SQL Server & Sybase Adaptive Server. jTDS is 100% pure Java (type 4) JDBC 3.0 driver for Microsoft SQL Server (6.5, 7, 2000, 2005, 2008 and 2012) and Sybase Adaptive Server Enterprise (10, 11, 12 and 15). jTDS is free software and released under the terms of the GNU LGPL.

The next steps are not required if you use Cache Monitor 2.81 or later because the driver and the configuration are already included!

To use this driver within Caché Monitor follow the next steps, please:

1. Download the driver and copy to the Caché Monitor folder
   Download the jTDS Driver from here https://sourceforge.net/projects/jtds/files/
   Navigate to the Caché Monitor installation folder, e.g. C:\Program Files (x86)\CacheMonitor and open the folder called “libs”. Create a new folder called “jtds” and copy the database driver into that folder. You find the driver file in the zip file you’ve downloaded before. The Driver file called like “jtds-1.3.1.jar”.
2. Register the driver file
   Navigate to the Caché Monitor installation folder, e.g. C:\Program Files (x86)\CacheMonitor and open the file “config.properties” with an editor and insert this lines:jdbc.jtds.drivername=jTDS for MS SQL Server & Sybase Adaptive Server
   jdbc.jtds.driverclass=net.sourceforge.jtds.jdbc.Driver
   jdbc.jtds.driverlib=lib/jtds/jtds-1.3.1.jar
   jdbc.jtds.sampleurl=jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;…]]
3. Select the driver and connect

Use the driver’s integrated security, which automatically absorbs the *current OS user’s* identity to verify with the DBMS at runtime.

To work with the Query Cloud you have to add your tables first to that virtual database. Go to all your source tables you want to combine and select “Add table to query cloud…”. No data will be copied. The query cloud only save information about the source of that tables:

After that you can navigate to the Query Cloud in Server Navigator. Open a new query editor on that node and work with all tables across the servers and namespaces:

Please watch this video for more details:

More features:

New data node “Security” with User and Role detail lists:

TableViewer: More details about Tables for Caché databases are available like extentsize, classname, external tables. The caching of the metadata is improved to boost performance.

All changes in detail:

There is no need to manually download-, register the driver or something like that. As already known all this is done by Caché Monitor. Just select “Add JDBC Connection…”

Known limitations:

The Query editor shows only the Caché keywords.

Only SQL Server authentication method works for SQL Server connections

HiDPI and Apple’s Retina Displays allow more pixels to be displayed on your screen. The result is that images display sharper; however, user interface controls may appear small and hard-to-read on high-density displays.

200% scaling solves this issue by doubling the size of the user interface. Enable this fature via “view” -> “usw HiDPI screen preferences”:

In the sql editor zooming via CTRL+Mousewheel is enabled

Known limitations:
Not all fonts are scaled for HiDPI support

The first time you click on the Database Diagrams folder of a database, you ask to “Create required objects to manage diagrams in this namespace?”.
It is not an error, but just a permission seeking dialog to create a database table that is necessary to work with database diagrams.
If you choose No then no table will be created and you will not be able to work with database diagrams.
If you choose Yes then a table would be created in your database and you will be able to work with database diagrams.If you modify any table outside the diagram editor, the changes will automatically be updated in any saved diagrams.

You can open database diagrams to view or edit the diagram’s structure. To open a database diagram in Server Navigator, expand the Database Diagrams folder.
Click the name of the database diagram you want to open.

You can create an image of a Database Diagram and copy it to another application. To copy a diagram image to the Clipboard open a Database Diagram.
Right-click a blank area and choose Copy Diagram to Clipboard.
