Unable to query SQL server 2008 databse from linux? - linux

I have written a JAVA SPRING RESTFUL web-service to query SQL server 2008 database using sqljdbc4 driver. It works fine from windows machine, but when I deploy the code to a Linux box I am not be to execute both select and insert queries.
I tried using “SET NOCOUNT ON”, but no luck.
Error while executing select query
org.springframework.jdbc.UncategorizedSQLException: StatementCallback; uncategorized SQLException for SQL [ Select statement ………. );]; SQL state [null]; error code [0]; The statement did not return a result set.; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.
Error while executing insert query
org.springframework.dao.DataAccessResourceFailureException: PreparedStatementCallback; SQL [Insert into log(id, datetime) values(?,?)]; SQL Server did not return a response. The connection has been closed.; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: SQL Server did not return a response. The connection has been closed.
JDBC driver POM dependency.
com.microsoft.sqlserver
sqljdbc4
4.0
I tried some other stuff that I read on google but no luck. If some can point me to a right direction, I would really appreciate help.

Try using jtds driver instead of microsoft jdbc driver.

Oracle: Why am I getting Error: ORA-00903: invalid table name when database table exists?

Background
I have a NodeJS server powered by ExpressJS that fetches data from Oracle database. I manage the database with Oracle SQL Developer tool. There is a database called MCF01 created using Database Configuration Assistant with pluggable database also named MCF01.
I connect to it using SYSTEM and the admin password both inside Oracle SQL Developer tool and from my server:
Now I created a table named CM_ITM_ALL:
CREATE TABLE "SYS"."CM_ITM_ALL" ...
I can without a problem query inside CM_ITM_ALL from Oracle SQL Developer tool like so:
Problem
I cannot execute the same query SELECT ITM_NM FROM CM_ITM_ALL WHERE ITM_NUM='a800004' using my nodejs server. What is the problem here?
Here is the error message from the Oracle via my server:
[Error: ORA-00942: table or view does not exist] {
errorNum: 942,
offset: 19
}
Table does exist. Connection is not a problem as it is giving out the table does not exist error. Otherwise it would give out wrong credentials error.
What I tried
Appending SYS into the query: SELECT ITM_NM FROM SYS.CM_ITM_ALL WHERE ITM_NUM='a800004'
Quoting the table name inside the query to SELECT ITM_NM FROM 'SYS'.'CM_ITM_ALL' WHERE ITM_NUM='a800004'
Dev environment
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0
NodeJS v16.13.0
ExpressJs 4.17.2
node-oracledb 5.3.0
Oracle SQL Developer 21.4.2

IBM AS400 File not Found error while the Table Object is still there

I'm relatively new to working with remote IBM databases. I am connecting to a remote IBM AS400 database using an ODBC Python3 connector in an Anaconda virtual environment on Windows 10. My connection that successfully works is:
import pyodbc
connection = pyodbc.connect(
Driver='{iSeries Access ODBC Driver}',
System='<host>',
database='<database>',
uid='<username>',
pwd='<password>')
c1 = connection.cursor()
print('Connection established')
After connecting I run this command to see the list of tables:
c1.execute("select table_name from sysibm.sqltables")
And I see all the tables that I would need to query. But then when I try to query the contents of a specific table using:
c1.execute("select * from <database>.<table> LIMIT 100")
I get an error:
ProgrammingError: ('42S02', '[42S02] [IBM][System i Access ODBC Driver][DB2 for i5/OS]SQL0204 - <table> der Art *FILE in <database> nicht gefunden. (-204) (SQLExecDirectW)')
(It's in German, it means table of type *FILE in database not found)
(And I'm not using angle brackets, it's just for demonstration)
But a software like DBeaver returns valid data for both of them, for the tables list query and the specific table query. It's only python that gives the error.
Can anyone point out what could I be doing wrong? Or what can I run to pinpoint the problem?
<database>.<table> is not correct.
On Db2 you have
database
-schema
--table
you should be using <schema>.<table> as the database has been specified in the connection string.
<database>.<schema>.<table> is supported when connecting to a remote database from the "local" one...but only for basic selects. Db2 for IBM i doesn't support for example joining between a "local" and remote table.

Error exporting SQL Server 2008 R2 database to Excel 2007

I was trying to export SQL Server 2008 R2 database to Excel 2007. I used the export wizard in SQL Server Management Studio. I used a query to export some columns of a table. I checked the query (saw the result of parsing it) and it was good. But on the REVIEW DATA TYPE MAPPING it showed error notifications. It was converting varchar to LongText. But when I executed the package it failed to run showing fail status for steps like prepare for execute,pre-execute,execute . the error message is like this
Error 0xc002f210: Preparation SQL Task 1: Executing the query "CREATE TABLE Query (
id Long, sku LongText..." failed with the following error: "Unexpected error from external database driver (1309).". Possible failure
reasons: Problems with the query, "ResultSet" property not set
correctly, parameters not set correctly, or connection not established
correctly.
(SQL Server Import and Export Wizard)
Someone has a clue whats wrong?
Not an ideal answer (I have no idea what the cause of this problem is) but I was able to bypass this error by saving the excel sheet to 97-03 format and extracting to that.

problem with the connectivity/updation using db2(universal driver)

I choosed a web project in order to do that i am using an IDE (Eclipse), database (DB2 universal driver) and Apache Tomcat server. So, by gods grace every thing has gone well but when I try to update data to DB2 database through JDBC code then I am getting an SQL DB error as
:: DB2 SQL error: SQLCODE: -204, SQLSTATE: 42704, SQLERRMC: DB2ADMIN.REGISTER
where register is my table name and even i logged in as db2admin but i think there is no connectivity established but still its not resolved
This sounds a bit strange, -204 is Function, procedure or trigger not found...
Have a look at SQLCODE concepts and use the SQL Message Finder link to check yr return code for a full explanation.
Note that DB2 procedures & functions have case-sensitive names.
Hope this helps.
