I am use Java to insert into a MSSQL database. I have column names with parentheses in them like Duration_(Mins).
I am trying to execute a statement like:
INSERT INTO mytable (Duration_(Mins)) VALUES (?)
and I am getting the following error:
Exception in thread "main" java.sql.SQLException: Incorrect syntax near '('
So I am guessing I need some way to "escape" the bracket?
For MS-SQL Server, this should work:
INSERT INTO mytable ([Duration_(Mins)]) VALUES (?)

I've code a simple hadoop/hive table defined as
CREATE TABLE mike
timeOne TIMESTAMP,
timeTwo TIMESTAMP,
name STRING
And then a myBatis mapper file to insert a record here that looks like this
<insert id="insertMikeFormDataForHadoop" parameterType="hashmap">
INSERT INTO ${tableName} (timeOne, timeTwo, name)
VALUES (#{timeOne, jdbcType=DATE}, #{timeTwo, jdbcType=DATE}, #{name})
</insert>
When I run a test to insert data via this SQL I get error like this.
org.apache.ibatis.exceptions.PersistenceException:
### Error updating database. Cause: org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: FAILED: ParseException line 2:16 mismatched input '-' expecting ) near '2017' in value row constructor
### The error may involve com.vertexinc.ve.returns.mapper.FormMapper.insertMikeFormDataForHadoop-Inline
### The error occurred while setting parameters
### SQL: INSERT INTO mike (timeOne, timeTwo, name) VALUES (?, ?, ?)
### Cause: org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: FAILED: ParseException line 2:16 mismatched input '-' expecting ) near '2017' in value row constructor
I've also tried this with jdbcType=TIMESTAMP instead of date with the same error.
I've wondering if I'm doing something wrong or assuming something about hive/hadoop and mybatis that I shouldn't.
(This is a super simple example I've used to illustrate this point).
Turns out this was an issue with the hive jdbc driver version 1.2.1.
The setTimestamp in the HivePreparedStatement had a small defect. Upgrading driver fixed the issue..

The following exception is thrown when ever I execute the following query
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '-name, cpy-address, cpy-contact) VALUES('nauman','ahmad18',12)' at line 1
Query which is causing exception
String query="insert into company(cpy-name, cpy-address, cpy-contact)VALUES(?,?,?)";
Connection con=DataAccessLayer.getConnection();
PreparedStatement stat=con.prepareStatement(query);
stat.setString(1, cname);
stat.setString(2, caddress);
stat.setInt(3,x );
int rowsAffected = stat.executeUpdate();
You cannot use - in SQL queries. Escape the column names using ` back quote or back tick characters.
insert into company(`cpy-name`, `cpy-address`, `cpy-contact`)VALUES(?,?,?)
On another note, if the database is in your control, change to column names to use '_' rather '-'. Having illegal characters and quoting them is not a good practice.
Hope this helps!
As #uday said you should change column name or use
" ` "
You can't use dash - symbol in SQL query in case of column name so that rename your column name or use Escape ` both side of column name and table name.
I am running following query:
my query = insert into tbl_name (ID,name, address,...)" +" values (?,?,?)
then I am using query runner class to insert.
myQueryRunnerObj.insert("my query",
result set handler obj,
generated id,
'my name',
'my address',...);
After this I am getting following exception: Exception in thread "main" java.sql.SQLException: ORA-00936: missing expression and sometimes invalid number of arguments expecting 11 given 10
What could be the reason to get this exception?
Correct syntax is:
INSERT INTO dept (deptno, dname) VALUES (dept_seq.nextval, 1);
or
INSERT INTO dept (deptno, dname)
SELECT dept_seq.nextval, 2
FROM dual;
ORA-00936: missing expression
Cause: A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.
Action: Check the statement syntax and specify the missing component.

Hi I'm executing this query in my java code and it tells me
org.postgresql.util.PSQLException: ERROR: column "st_srid" does not exist
However when I run it directly in pgAdmin it shows me the column and the value inside.
Here is my query:
"Select Distinct ST_SRID(shape) from TableName where shape IN (SELECT shape from TableName)"
I appreciate any help
Distinct needs parenthesis around the st_srid function call.
I am using Oracle 11g, I am executing Oracle sql script through java code. My SQL script may contain SQL statements(DDL or DML) or PL/SQL blocks, so I don't want to parse the script in my java code but used This solution to execute complete script at once. Following is the sample code, where SQLExec class is in ant jar.
This solution worked for most cases except that if sql script contains create or replace trigger it fails with java.sql.SQLSyntaxErrorException: ORA-00900: invalid SQL statement. I have also specified snippet of sql script which fails.
Please note that if I run same script through SQL Developer, it runs fine.
Following is the Java code:
private void executeSql(String sqlFilePath) {
final class SqlExecuter extends SQLExec {
public SqlExecuter() {
Project project = new Project();
project.init();
setProject(project);
setTaskType("sql");
setTaskName("sql");
}
}
SqlExecuter executer = new SqlExecuter();
executer.setSrc(new File(sqlFilePath));
executer.setDriver(args.getDriver());
executer.setPassword(args.getPwd());
executer.setUserid(args.getUser());
executer.setUrl(args.getUrl());
executer.execute();
}
SQL Script snippet:
......
......
CREATE OR REPLACE TRIGGER MY_TRG
BEFORE INSERT ON MY_TABLE
FOR EACH ROW
BEGIN
:NEW.MYNUMBER := MY_SEQUENCENUM.NEXTVAL;
END;

In the documentation it says:
Multiple statements can be provided, separated by semicolons (or the defined delimiter).
Therefore, using the semicolon character (;) as the default delimiter, SQLEXEC interprets the CREATE TRIGGER statement of your script as two statements, giving this error message as the result.
As #Reza Goodarzi mentioned the cause of invalid SQL statement is semicolon being used as the statement separator. So to solve my issue I am separating each statement with slash(/) as delimiter and followed these rules which I created myself:
Each SQL statement (not part of PL/SQL block) and PL/SQL block must end with a forwarded slash (/) in a new line.
SQL statement (not part of PL/SQL blocks) should not end with semicolon (;). I just removed semicolon from the end of statements.
For PL/SQL block do not remove the semicolon(;) from end of the block as well as from any statement contained within the block.
And by making these changes in my SQL Scripts I executed (using jdbc) each PL/SQL block and each SQL statement (not part of PL/SQL block) at a time by parsing the file myself instead of using SQLExec or any other external api/library.
I think you need to change your trigger to set your new ID
create or replace trigger MY_TRG
BEFORE insert MY_TABLE
for each row
begin
if (:new.MYNUMBER is null) then
select MY_SEQUENCENUM.nextval
into :new.MYNUMBER
from DUAL;
end if;
end;
/
or this:
create or replace trigger TG_BIU_TABLE1
before insert or update on TABLE1
for each row
begin
if (:new.ID1 is null) then
select SQ_TABLE1.nextval
into :new.ID1
from DUAL
end if
end
/
You can also add a delimiter in the execute statement, as so:
......
......
DELIMITER $$
CREATE OR REPLACE TRIGGER MY_TRG
BEFORE INSERT ON MY_TABLE
FOR EACH ROW
BEGIN
:NEW.MYNUMBER := MY_SEQUENCENUM.NEXTVAL;
END; $$
......
I also left the final part of the script just for the triggers and procedures, as the delimiter is used onward.
