![]() ![]() Exactly what statement to run depends on the database. an SQL statement that is run whenever you connect or disconnect to a database. Second, place the sourcestring followed the FROM clause. If you do not specify trimcharacter the TRIM function will remove the blank spaces from the source string. Please refer to the driver documentation for more information.įinally, you can create a connection hook, i.e. Code language: SQL (Structured Query Language) (sql) First, specify the trimcharacter, which is the character that the TRIM function will remove. Some drivers offer properties for setting read-only mode (see example below). The effect of this is not guaranteed the server may silently ignore this setting and still operate in read/write mode. Note: this will only affect SQL Commander and will not prevent operations like "Alter Table" when called from a menu.ĭepending on the database and JDBC driver, you may be able to set the session in read-only mode by defining the connection property = true (see Configuring Connection Properties). You can change this to Deny for extra safety. Provide the database details: Driver Class: org.h2.Driver JDBC URL: jdbc:h2:/h2 'file path' User Name: 'blank by default' Password: 'blank by default'. It will show the console of the H2 database on the browser. Three-part names must be specified for pass-through queries that use the SQL Server Native Client OLE DB provider. If the provider supports only catalog names, a three-part name of the form must be specified. ![]() ![]() The default settings for the Production type will prompt for confirmation before doing any write operations. then in the bin directory of H2 open a command prompt and run the command java -jar in my case it is. If the provider supports only schema names, a two-part name of the form schema.object must be specified. Modify the connection properties and set the desired type ( Development/ Test/ Production) and then define permissions in the SQL Commander to prevent all write operations. Is there a way to display CLOB/BLOB data in the Cell Form only as text Im currently dealing with a lot of BLOB data with XML headers and when I double. This said, depending on your JDBC Driver and the server you connect to, DbVisualizer can offer some help. There is no way to securely prevent write operations from the client. A proper security solution must be implemented by the DBA at the server using roles and permission. ![]()
