MS SQL Server
Set connection properties for i-net Merlia JDBC driver.
Basic Settings
| Name | Description |
|---|---|
| User | The user of the database. |
| Password | The database user's password. If you mark this, your password will be stored when the report is saved. Otherwise it will only be held temporarily in memory until the program is closed. Stored passwords are encrypted, but could possibly be decrypted. When exporting a configuration, passwords will be only be exported if they are marked to be saved. |
| Host | The name or IP address of server the database is located. |
| Instance name | If more then one Sql Server run on a system, the further server have to accessed by instance name, because the port is often unknown. |
| Database | The catalog of the database. |
Optional Settings
| Name | Description |
|---|---|
| Port | The port Sql Server is listening. |
| Secure level | set the level of security with SSL. Default is 1; If you want to use SSL (Secure Sockets Layer) with i-net JDBC drivers and the MS SQL Server then you need to install:
|
| Use server cursor always | If set to "true", executeQuery() uses server cursors always. Default is "false" |
| Login Timeout | Override the value from DriverManager.getLoginTimeout(). |
| Query Timeout | Sets the query timeout. Default is 5 * loginTimeoutSet the default query timeout for all Statements. |
| Daylight saving time | Effects the way timezone offset is calculated. The ways differ in speed and safety. If true the slower way is used, but this way is bug free. If false, the faster way is used (2-3 times faster), but this way has a Java bug for some time zones at the day the day saving time switches. The bug there is a time displacement of one hour for some hours of the day. |
| Charset | Set here a Java charset name if Strings in database are coded in a special format. Character converting is disabled per default. |
Compatibility Settings
| Name | Description |
|---|---|
| database catalog | Override the database catalog of the tables, views and procedures in the report design. |
| database schema | Override the database schema of the tables, views and procedures in the report design. |
| supports SQL92 | Indicates whether the SQL statement can contain the join condition in SQL92 syntax or not. |
| supports WHERE clause | Indicates whether the SQL statement can contain the WHERE clause or not. This flag is relevant if tables and one Datasource is used only. |
| supports ORDER BY clause | Indicates whether an ORDER BY clause is allowed for the SQL statement. This flag is relevant if tables and one Datasource is used only. |
| supports brackets in join | Indicates whether parentheses are allowed in FROM clause of the SQL statement. For example the SAPDB does not support parentheses in JOIN syntax. This flag is relevant if tables and one Datasource is used only. |
| quote database identifier | Indicates whether table names and column names have to be quoted if they contain characters in lower case. This property can be necessary for Oracle databases for example, if table/column were created with quotes and lower case characters. |
| identifier quote character | This property is to adapt the SQL statement for a specific database. The set string is used to quote SQL identifiers. For most databases it is a ["] character. By default, i-net Clear Reports requests this information from the database. |
| alias keyword | This property is to adapt the SQL statement for a specific database. Set the SQL keyword that will be put between table name and table alias. E.g. the database PostgreSql requires the keyword "AS". Many databases do not need a special keyword to indicate that a alias name is about to follow. |
| escape whole identifiers | This flag is to adapt the SQL statement for a specific database. This flag influences the way SQL identifier are written to SQL statement. By default it is false and should be kept false for most databases. If the flag is set to true, the complete table identifier will enclosed with quotes. If the table identifier contains catalog/schema informations, then the complete expression will enclosed with quotes. Example - escape everything is true: the original table identifier is "atable" in catalog "aCatalog". The resulting expression for the table in the SQL statement will be : "select ... from "aCatalog.aTable" " note: this syntax is not allowed for most of databases. The only known case setting this flag to true is using i-net FOSITEX driver for csv data files. |
| validation query | This property can be used to specify a certain SQL statement which will be executed for validation of the database connection. If this statement can be executed without an error the connection is assumed to be valid. If an error occurs then the connection will be handled like a closed one. If this property is not set no special SQL statement will be executed for validation of the connection. Only java.sql.Connection.isClosed() will be called. |
| initSQL | This property can be used to specify a certain SQL statement which will be executed after the database connection has been established. E.g. for Oracle databases the session can be forced to use bind variables. |
