Create table as select with parameter using jdbcTemplate

I want to use jdbcTemplate to create table based on another table under condition. I have postgres database. When I execute this and pass parameter:
String SQL = "create table test as (select * from users where countryId =?)";
jdbcTemplate.update(SQL, new Object[] {3})
I receive table test with all columns from users table but with no rows.
However, when I execute this:
String SQL = "create table test as (select * from users where countryId =3)";
jdbcTemplate.update(SQL)
I receive test table with rows where countryId = 3, so that is what I was expecting to receive in the first solution.

Your passing of the bind variable is not correct, but it does not play any role.
You simple can not use a bind variable in a data definition statement as you immediately see in the triggered error
Caught: org.springframework.jdbc.UncategorizedSQLException:
PreparedStatementCallback; uncategorized SQLException for SQL
[create table test as (select * from users where countryId =?)];
SQL state [72000]; error code [1027];
ORA-01027: bind variables not allowed for data definition operations
So you have two options, either concatenate the statement (which is not recommended due to the danger of SQL injection)
or split the statement in two parts:
// create empty table
sql = "create table test as (select * from users where 1 = 0)";
jdbcTemplate.update(sql)
// insert data
sql = "insert into test(countryId, name) select countryId, name from users where countryId =?";
updCnt = jdbcTemplate.update(sql, new SqlParameterValue(Types.INTEGER,3));
Note that in the insert statement you can see the correct way of passing an interger value of 3 as a bind variable.

You can follow below approach as well:-
jdbcTemplate.execute("CREATE TABLE IF NOT EXISTS employee_tmp (id INT NOT NULL)");
List<Object[]> employeeIds = new ArrayList<>();
for (Integer id : ids) {
employeeIds.add(new Object[] { id });
}
jdbcTemplate.batchUpdate("INSERT INTO employee_tmp VALUES(?)", employeeIds);
Here you may query with 2 operations to avoid SQL injection.

You are using method update from jdbcTemplate in a wrong way.
Try with this:
String SQL = "create table test as (select * from users where countryId = ?)";
jdbcTemplate.update(SQL, 3);

Java dynamically generate SQL query - ATHENA

I am trying to generate sql query based on user input. There are 4 search fields on the UI:
FIRST_NAME, LAST_NAME, SUBJECT, MARKS
Based on user input I am planning to generate SQL query. Input can be of any combination.
eg: select * from TABLE where FIRST_NAME="some_value";
This query needs to be generated when FIRST_NAME is given and other fields are null
select * from TABLE where FIRST_NAME="some_value" and LAST_NAME="some_value";
This query needs to be generated when FIRST_NAME and LAST_NAME are given and other fields are null
Since there are 4 input fields, number of possible queries that can be generated are 24 (factorial of 4).
One idea is to write if condition for all 24 cases.
Java pseudo code:
String QUERY = "select * from TABLE where ";
if (FIRST_NAME!=null) {
QUERY = QUERY + "FIRST_NAME='use_input_value';"
}
if (LAST_NAME!=null) {
QUERY = QUERY + "LAST_NAME='use_input_value';"
}
if (SUBJECT!=null) {
QUERY = QUERY + "SUBJECT='use_input_value';"
}
if (MARKS!=null) {
QUERY = QUERY + "MARKS='use_input_value';"
}
I am not able to figure out how to generate SQL queries with AND coditions for multiple Input values.
I have been through concepts on dynamically generate sql query but couldn't process further.
Can someone help me on this.
FYI: I have been through How to dynamically generate SQL query based on user's selections?, still not able to generate query string based on user input.

Let's think about what would happen if you just ran the code you wrote and both FIRST_NAME and LAST_NAME are provided. You'll wind up with this:
select * from TABLE where FIRST_NAME='use_input_value';LAST_NAME='use_input_value';
There are two problems here:
The query is syntactically incorrect.
It contains the literals 'use_input_value' instead of the values you want.
To fix the first problem, let's first add and to the start of each expression, and remove the semicolons, something like this:
String QUERY = "select * from TABLE where";
if (FIRST_NAME!=null) {
QUERY = QUERY + " and FIRST_NAME='use_input_value'";
}
Notice the space before the and. We can also remove the space after where.
Now the query with both FIRST_NAME and LAST_NAME will look like this:
select * from TABLE where and FIRST_NAME='use_input_value' and LAST_NAME='use_input_value'
Better but now there's an extra and. We can fix that by adding a dummy always-true condition at the start of the query:
String QUERY = "select * from TABLE where 1=1";
Then we append a semicolon after all the conditions have been evaluated, and we have a valid query:
select * from TABLE where 1=1 and FIRST_NAME='use_input_value' and LAST_NAME='use_input_value';
(It may not be necessary to append the semicolon. Most databases don't require semicolons at the end of a single query like this.)
On to the string literals. You should add a placeholder instead, and simultaneously add the value you want to use to a List.
String QUERY = "select * from TABLE where";
List<String> args = new ArrayList<>();
if (FIRST_NAME!=null) {
QUERY = QUERY + " and FIRST_NAME=?";
args.add(FIRST_NAME);
}
After you've handled all the conditions you'll have a string with N '?' placeholders and a List with N values. At that point just prepare a query from the SQL string and add the placeholders.
PreparedStatement statement = conn.prepareStatement(QUERY);
for (int i = 0; i < args.size(); i++) {
statement.setString(i + 1, args[i]);
}
For some reason columns and parameters are indexed starting at 1 in the JDBC API, so we have to add 1 to i to produce the parameter index.
Then execute the PreparedStatement.

Commons DBUtils Oracle 11.2.0.4 with Java 1.7 Binding parameters SQLException ORA-00942

I'm working with Oracle Database 11.2.0.4 with ojdbc6.jar, and I'm using apache commons dbutils v1.7, with JDK 7. So I'm using the QueryRunner and its method in this function
private <T> List<T> executeQueryAndReturnBeanList(String query, Class<T> className, Object... param) throws SQLException {
Connection connection = getDBConnectionInstance();
DbUtils.loadDriver("oracle.jdbc.driver.OracleDriver");
ResultSetHandler<List<T>> beanListHandler = new BeanListHandler<>(className,new BasicRowProcessor(new GenerousBeanProcessor()));
QueryRunner runner = new QueryRunner();
List<T> list = runner.query(connection, query, beanListHandler, param);
return list;
}
and everything works fine with select query without binding parameters
SELECT * FROM PEOPLE WHERE GRUPPO = 1 AND LANG = 'en_US'
But when I excute this query
String query = "SELECT * FROM PEOPLE WHERE GRUPPO = ? AND LANG = ?";
It gives me this SQL Exception
java.sql.SQLException: ORA-00942: table or view does not exist
Query: SELECT * FROM PEOPLE WHERE GRUPPO = ? AND LANG = ? Parameters: [1, en_US]
at org.apache.commons.dbutils.AbstractQueryRunner.rethrow(AbstractQueryRunner.java:527)
at org.apache.commons.dbutils.QueryRunner.query(QueryRunner.java:391)
at org.apache.commons.dbutils.QueryRunner.query(QueryRunner.java:252)
at mypackage.executeQueryAndReturnBeanList(JDBCFunctions.java:199)
I really don't know why. I tried to use :P1, :P2 or :1, :2 instead of ? to bind parameters but nothing it happens. Any ideas?

Group is a reserved word and cannot be used as a column or table name. Most probably you have a quoted column name such as "GROUP" within the table.
So, need to query as
SELECT * FROM PEOPLE WHERE "GROUP" = 1 AND LANG = 'en_US'
Quoted table names should be case sensitive, unlike unquoted ones.
The above one is the basic mistake, while the error(ORA-00942) suggests that your application connects to different schema than the schema in which successfully tested the query.

I finally found the solution. I inserted " on every column and table's name and now it works. For example:
String query = "SELECT * FROM \"PEOPLE\" WHERE \"GRUPPO\" = ? AND \"LANG\" = ?"

Issue converting PostgreSQL query to DSLContext

I am trying to convert a query I wrote and tested from the command line to a DSLContext query using jOOq and am encountering issues. The query below is intended to return a list of tags that match the like parameter with a wildcard from a table "campaign" with a JSONB column "tags". This column has values formatted in the following way:
["dogs","cats","rabbits"]
select distinct A.value
from campaign T, LATERAL jsonb_array_elements_text(T.tags) A
where A.value LIKE 't%'
I am attempting to create this to a DSLContext in the following manner but I get an error "ERROR: argument of AND must not return a set". Can anyone see what I can do to resolve this issue and produce the same results from my PostgreSQL query and my DSL query below?
final Field<String> tagField = field("jsonb_array_elements_text(tags)", String.class);
final Table<Record1<String>> lateral =
lateral(sql.dsl().select(a).from(CAMPAIGN)).asTable();
final Result<Record1<String>> tag = sql.dsl()
.select(tagField)
.from(CAMPAIGN, lateral)
.where(tagField.like("t"))
.fetch();

Your query would translate to jOOQ as such:
Field<String> value = field(name("A", "value"), String.class);
sql.dsl()
.selectDistinct(value)
.from(
CAMPAIGN,
lateral(table("jsonb_array_elements_text({0})", CAMPAIGN.TAGS)).as("A"))
.where(value.like("t%"))
.fetch();

Multiple parameters to SQL JdbcTemplate

I have query like
`Select * from Table1 where xyz in (List of String to be Supplied).
In my java code. I have a dao object in which I am calling this sql using jdbc template.
The method takes in a list of String and that needs to be supplied to this SQl. I have my row-mapper.
How to write the SQl and how to pass the list of variables?
My SQL will run on a Teradata Db.

Use a NamedParameterJdbcTemplate which, as the doc says:
It also allows for expanding a List of values to the appropriate number of placeholders.
So you just need
String sql = "select * from Table1 where xyz in :list";
// or String sql = "select * from Table1 where xyz in (:list)";
// I can't remember which one is right
Map parameters = new HashMap<String, Object>();
parameters.put("list", theListOfXyz);
List<Foo> result = template.query(sql, parameters, rowMapper);
