sqlstring | Simple SQL escape and format for MySQL | Runtime Evironment library

Your question does not show your real code so I cannot guess what mistake or omission that you are making.

Named Parameters work well with DB2PreparedStatement, as long as you follow the documented rules, and you are using a currently supported version of the Db2-server and a currently supported version of the type4 db2jcc4.jar driver.

IBM provides a working example of using named parameter markers with a Type-4 jdbc connection, in the file TbSel.java .

The sample code is here, and on github, and in your Db2-LUW server ~$DB2INSTANCE/sqllib/samples/java/jdbc directory (if the samples programs are installed). You can study these, and the readme that accompanies the samples, and build them yourself.

In that example code, IBM enables the named parameter markers programatically: (you can also enable them via a connection string attribute ;enableNamedParameterMarkers=1;

I found the solution. Basically add the host ip and port infront of the /health in the AddHealthCheckEndpoint override. Remember http and https are not interchangeable so use the correct one based on what you configured in IIS.

AddUrlGroup has an overload that allows you to specify the method through the httpMethod parameter. Try using :

trigger-identity generator is not supported by dynamic insert dynamic-insert="true". Related bug report: https://github.com/nhibernate/nhibernate-core/issues/1062

So just disable dynamic insert for your entity and it should work (dynamic-insert="false").

There is a number of problems with your code.

1. As mentioned in the comments, you need a Schema.ini file for your code to work. - I assume you have got one already because otherwise your code would only work if the text file matches the default settings of the Text Driver.
2. The On Error Resume Next statements, particularly the second one, in your code are most likely the reason why you do not see any error message.
3. The column names and data in the text file will be treated case sensitive. So your LCase(sqlstring) is not a good idea unless the text file content is all lower case.

I changed the datatype of taxper to float and it worked. I found this after checking the err from rows.Scan( as suggested by @mkopriva

Without a query builder library (e.g. Knex), you'll need to

• form the SQL query (as a string)
• put the parameters into place

e.g. something like this:

Only one method in RelBuilder uses a RelOptSchema: scan(String...) (and its variant Scan(Iterable)). Which makes sense when you consider that the purpose of RelOptSchema is as a directory service, converting a table name (or table path, consisting of a table name qualified with catalog and/or schema names) into a RelOptTable object.

If you have 'free-standing' table objects that are not accessed via a namespace then you can create TableScan relational expressions directly and then call RelBuilder.push(RelNode) to add them to the stack. Since you never call RelBuilder.scan you can create RelBuilder with a null RelOptSchema.

But in your case, it looks as if you don't have free-standing table objects. That's a problem for Calcite, because it needs to know that your "EMP" table has a field called "DEPTNO" and it has type INTEGER.

So I suggest that you create a 'virtual' schema that contains type information but is not necessarily backed by real tables. The MockCatalogReader class, used in several of Calcite's tests, is a good example to follow.

For the array, try:
