I am running the following update command:
NpgsqlCommand command = new NpgsqlCommand("UPDATE \"FPConfig_simulationresult\" SET key_name = :keyName WHERE id = :resultID", conn);
command.Parameters.Add(new NpgsqlParameter("keyName", DbType.String));
command.Parameters.Add(new NpgsqlParameter("resultID", DbType.Int32));
command.Parameters[0].Value = keyName;
command.Parameters[1].Value = resultID;
int rowsAffected = command.ExecuteNonQuery();
and get the error:
ERROR: 42601: syntax error at or near "="
I have checked everything in the update SQL statement, the table name and field names are correct.

When trying to call procedure with timestamp parameters by the code:
SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(dataSource)
.withSchemaName("time_series")
.withProcedureName("refresh_continuous_aggregate")
.declareParameters(new SqlParameter("continuous_aggregate", Types.VARCHAR),
new SqlParameter("window_start", Types.TIMESTAMP),
new SqlParameter("window_end", Types.TIMESTAMP));
MapSqlParameterSource inParams = new MapSqlParameterSource()
.addValue("continuous_aggregate", "time_series.current_data_hourly", Types.VARCHAR)
.addValue("window_start", "2020-11-12 01:02:03.123456789", Types.TIMESTAMP)
.addValue("window_end", "2021-02-12 01:02:03.123456789", Types.TIMESTAMP);
Map<String, Object> execute = simpleJdbcCall.execute(inParams);
I'm getting error:
ERROR o.s.i.handler.LoggingHandler ->
org.springframework.jdbc.BadSqlGrammarException:
CallableStatementCallback; bad SQL grammar [{call
time_series.refresh_continuous_aggregate(?, ?, ?)}]; nested exception
is org.postgresql.util.PSQLException: ERROR: could not determine data
type of parameter $2
The similar error I'm getting when I try to use native query with dynamic parameters:
String queryStr = "CALL time_series.refresh_continuous_aggregate(?1, ?2, ?3)";
Query query = entityManager.createNativeQuery(queryStr)
.setParameter(1, continuousAggregate)
.setParameter(2, windowStart, TemporalType.TIMESTAMP)
.setParameter(3, windowEnd, TemporalType.TIMESTAMP);
Object singleResult = query.getSingleResult();
ERROR o.h.e.jdbc.spi.SqlExceptionHelper -> ERROR: syntax error at or
near "$2"
And by using StoredProcedureQuery:
StoredProcedureQuery query = entityManager.createStoredProcedureQuery("time_series.refresh_continuous_aggregate")
.registerStoredProcedureParameter("continuous_aggregate", String.class, ParameterMode.IN)
.registerStoredProcedureParameter("window_start", Date.class, ParameterMode.IN)
.registerStoredProcedureParameter("window_end", Date.class, ParameterMode.IN)
.setParameter("continuous_aggregate", "time_series.current_data_hourly")
.setParameter("window_start", new Date(), TemporalType.TIMESTAMP)
.setParameter("window_end", new Date(), TemporalType.TIMESTAMP);
query.execute();
WARN o.h.e.jdbc.spi.SqlExceptionHelper -> SQL Error: 0, SQLState:
42P18 ERROR o.h.e.jdbc.spi.SqlExceptionHelper -> ERROR: could not
determine data type of parameter $2
It looks like JDBC drivers issue.
I have a psycopg2 connection which I am using to connect to postgresql from pyspark. Here is my code -
host = 'IP Address'
port = 'Port'
user = 'postgres'
db = 'postgres'
password = 'password'
def move_records(main_table,stg_table):
try:
connection = psycopg2.connect(host=host,
database=db,
user=user,
password=password,
#driver = driver,
port = port)
cursor = connection.cursor()
move_query = "INSERT INTO " +main_table+ " select * from "+stg_table+" where country ='USA'"
cursor.execute(move_query)
connection.commit()
logger.debug("Record moved successfully")
except (Exception, psycopg2.DatabaseError) as error :
logger.error("%s Error in transction Reverting all other operations of a transaction ", error)
global flag
flag = False
connection.rollback()
finally:
if(connection):
cursor.close()
connection.close()
logger.debug("PostgreSQL connection is closed")
move_records(table_1,table_2)
But I keep getting error below error on line if(connection):
"UnboundLocalError","evalue":"local variable 'connection' referenced before assignment"
Can not figure out what is the issue. Need help.
I am no expert in Python but I have worked on similar thing, connecting from Python to Postgres in in AWS Lambda using psycopg2.
I believe the error lies somewhere in scope of variable. You need to declare all variables(host, port, user, db, password) inside function once again as global or nonlocal and then try to run function.

I'm having a problem, whenever I try to run the code below and select the statement 2 to insert a tool and put a random tool name I get the error message : ProgrammingError('column "inserttool' does not exist\nLine 1: insert tools(tool_name, rental_days) values(#insertTool, '2') .
Here is the code :
if Menu == "2":
cursor = connection.cursor()
InsertTool = raw_input("Please insert the tool that you want to add.\n")
insert_tool = """insert into tools(tool_name, rental_days) values(#InsertTool, '2')"""
try:
cursor.execute( insert_tool);
connection.commit();
print("Tool is succesfully inserted!")
except Exception as e:
connection.rollback();
print("Exception Occured : ",e)
connection.close();
try this.
if Menu == "2":
cursor = connection.cursor()
InsertTool = raw_input("Please insert the tool that you want to add.\n")
insert_tool = """insert into tools(tool_name, rental_days) values(%s, %s)"""
val = (InsertTool, "2")
try:
cursor.execute(insert_tool, val);
connection.commit();

You have two where and two = in your update query.
val query2 = "Update audit Set status='test' where product='D'"
I am using Typehandler to map a List<Dep> to oracle array of ... here is the setPArameter method in the handler :
public void setParameter(PreparedStatement ps, int i, List<Dep> parameter, JdbcType jdbcType)
throws SQLException {
Connection connection = ps.getConnection();
// StructDescriptor structDescriptor = StructDescriptor.createDescriptor("MEMS_ARR", connection);
Struct[] structs = null;
if(parameter != null && parameter.size() >0) {
structs = new Struct[parameter.size()];
for (int index = 0; index < parameter.size(); index++)
{
Dep dep = parameter.get(index);
Object[] params = new Object[7];
params[0] = dep.getOrder();
params[1] = dep.getIdTp;
params[2] = dep.getId();
params[3] = " ";
params[4] = " ";
params[5] = " ";
params[6] = " ";
// STRUCT struct = new STRUCT(structDescriptor, ps.getConnection(), params);
structs[index] = connection.createStruct("MEMS", params);
}
// ArrayDescriptor desc = ArrayDescriptor.createDescriptor("MEMS_ARR", ps.getConnection());
// ARRAY oracleArray = new ARRAY(desc, ps.getConnection(), structs);
}else {
parameter = new ArrayList<DependentDTO>();
structs= new Struct[0];
}
this.parameter = parameter;
Array oracleArray = ((OracleConnection) connection).createOracleArray("MEMS_ARR", structs);
ps.setArray(i, oracleArray);
}
and here is the MEMS type :
create or replace TYPE MEMS AS OBJECT
( MEM1 NUMBER(2,0),
MEM2 VARCHAR2(1),
MEM3 VARCHAR2(15),
MEM4 VARCHAR2(60),
MEM5 VARCHAR2(1),
MEM6 VARCHAR2(40),
MEM7 VARCHAR2(10)
);
and here is the portion of the xml mapping file that uses the Typehandler :
#{nat,javaType=String,jdbcType=VARCHAR,mode=IN}, --nat
**#{deps,javaType=List,jdbcType=ARRAY,mode=IN,jdbcTypeName=MEMS_ARR,typeHandler=com.my.package.MyHandler}, --mems**
#{res,javaType=String,jdbcType=VARCHAR,mode=OUT} --res
the error log is as follows :
Error querying database. Cause: java.sql.SQLException: ORA-06550: line 31, column 5: PLS-00103: Encountered the symbol "" when expecting one of the following: . ( ) , * # % & = - + < / > at in is mod remainder not rem => <an exponent (**)> <> or != or ~= >= <= <> and or like like2 like4 likec between || indicator multiset member submultiset The symbol "(" was substituted for "" to continue. ORA-06550: line 44, column 4: PLS-00103: Encountered the symbol ";" when expecting one of the following: .

As you can see in the logs, the mems is replaced by empty string or is merged with the next arg res ... the comma is not there
Also kindly note that I already debugged inside the mybatis code and realized that the mapping setParameter method is called and the input List is mapped correctly to the oracle array ... the issue happens at the time of real calling
The issue actually was that I simply missed one comma between two previous parameters ... but the error pointed to the wrong parameter to look at
