Inserting single quote in JDBC for SQL Query not working

I'm having issues dealing with the single quote while using it in a prepared statement in JAVA via Oracle JDBC.
Let's say we have a table Restaurant with a column restaurant_name with 1 value : Jack's Deli
I want to use a simple prepared statement query like this:
String result = "Jack\'\'s Deli"
String sqlStatement = "select * from Restaurant where restauraunt_name like ? escape '\\' ";
PreparedStatement pStmt = conn.prepareStatement(sqlStatement);
pstmt.setString(1, result);
The result shows 0 returned values, however when I directly search the query in the database (ORACLE) it works fine and retrieves the result. (Oracle uses two single quotes as an escape for the first)
I am thinking that the value is not being passed properly to the database. Or there is some other formatting issue.

The point of prepared statements is that you don't need any escaping.
.setString(1, "Jack's Deli") will get it done.

Output parameter from SQL Server stored procedure truncated at 4000 characters

I have a problem with the output parameter of a stored procedure when it contains more than 4000 characters. The response seems to be truncated by the JDBC driver? How can I get the full result?
The stored procedure answers with the complete response (> 4000 characters) but I can not open it from Java. I have tried both jTDS and Microsoft's JDBC driver 6.0. Here is my code:
CallableStatement pstmt = con.prepareCall("{call sp_horus_get_consultorios_stv(?)}");
pstmt.registerOutParameter(1, -1);
pstmt.setString(1, "");
pstmt.execute();
String sp_horus_get_consultorios_stv = pstmt.getString(1);
This works with stored procedures in sybase.

I was able to recreate your issue using Microsoft JDBC Driver 6.x. I found that I could avoid the problem by commenting out the setString call:
try (CallableStatement pstmt = conn.prepareCall("{call usp_horus_get_consultorios_stv(?)}")) {
pstmt.registerOutParameter(1, Types.LONGNVARCHAR);
//pstmt.setString(1, ""); // disabled
pstmt.execute();
String sp_horus_get_consultorios_stv = pstmt.getString(1);
System.out.println(sp_horus_get_consultorios_stv.length()); // > 4000 characters
}
Unfortunately, that fix did not solve the problem under jTDS 1.3.1. It appears that jTDS still suffers from the limitation described here. So, for jTDS it appears that we have to do something like this:
String sql =
"DECLARE #out NVARCHAR(MAX);" +
"EXEC usp_horus_get_consultorios_stv #out OUTPUT;" +
"SELECT #out;";
try (
Statement st = conn.createStatement();
ResultSet rs = st.executeQuery(sql)) {
rs.next();
String sp_horus_get_consultorios_stv = rs.getString(1);
System.out.println(sp_horus_get_consultorios_stv.length()); // > 4000 characters
}

From what I understand, your output parameter is of type NVARCHAR(8000), which is the maximum explicit number allowed, and outputs a 4000 character Unicode string lenght (2 bytes per char).
However, and lucky you, there another possibility : NVARCHAR(MAX), that basically allows an infinite string lenght (well, not infinite, but almost :
What is the maximum number of characters that nvarchar(MAX) will hold?
You should change your output paramater type to NVARCHAR(MAX).
Happy coding ;)

"UcanaccessSQLException: unexpected token" when column name contains apostrophe

I am converting an existing program from JDBC-ODBC Bridge to UCanAccess. It has been working for years. The Java program writes to an MDB file. After conversion, one Insert command stopped working.
It throws "net.ucanaccess.jdbc.UcanaccessSQLException: unexpected token: [".
After some experimentation I determined that the problem is caused by three columns that include apostrophes in their names. Example: [Sched'd PO Place Date]. Apparently JDBC-ODBC Bridge did not care but UCanAccess does.
I am somewhat trapped with the existing MDB structure or I'd simply rename the fields. But there is no telling how many downstream reports could be broken if I did that. The MDB is used for Ad Hoc reporting.
Here is a simplified SQL Select version of the problem. It throws the same error as the Insert.
String cJD = "net.ucanaccess.jdbc.UcanaccessDriver";
String cS = "jdbc:ucanaccess://C:/MosAll/mosall.mdb";
String uid = "";
String pw = "";
String sql4 = "select [Sched'd PO Place Date] from [Tier 1] ";
Class.forName(cJD);
Connection con = DriverManager.getConnection(cS, uid, pw);
PreparedStatement pstmt4;
pstmt4 = con.prepareStatement(sql4);
pstmt4.execute();
Is there a way to "escape" the apostrophes or reconfigure ucanaccess so that the driver can execute them?

This issue has been fixed in UCanAccess 2.0.9.4.
Previous answer:
I have been able to recreate the issue with UCanAccess version 2.0.9.3.
select [Sched'd PO Place Date] ...
fails, but for now simply omitting the '
select [Schedd PO Place Date] ...
works okay. Interestingly, using backticks instead of square brackets
select `Sched'd PO Place Date` ...
also produces the exception
net.ucanaccess.jdbc.UcanaccessSQLException: unexpected token: [
With luck this will get fixed in a future release of UCanAccess.

have you tried table, columns names between `` (they not apostrophe but the one next to ~), the \' may work, and finally the JDBC standard way is to define the escape character at the end of the query:
String sql4 = "select [Sched\'d PO Place Date] from [Tier 1] { escape '\'}"
You may want to try the one above also with ``instead of []
Finally, your last resource is "select *" and extract the right column yourself

JDBC PreparedStatement with "?" in the column name

I am using a JDBC connection to fetch data from an Access database.
The database design is not my control. In the database there are columns that have "?" included in their names, for example: Open?, Paid?, and lots more.
When I try to fetch data with a PreparedStatement it gives me an error. The query is:
SELECT Open? FROM tblJobList WHERE WeekEnding=?
I also tried to use brackets like [Open?], but the result is the same.
The error I receive is "Too few parameters ..." as I am pushing only one parameter into the PreparedStatement.
I can not use normal statement because of WeekEnding=? as this value is a Timestamp and I could not manage to work it with Statement. Only prepared statement works here.
Can anyone tell me how to use these kind of column names in a PreparedStatement?

use the " character
"SELECT \"Open?\" FROM tblJobList WHERE WeekEnding=?"
tested this against oracle and appears to work with mssqlserver
How to select a column in SQL Server with a special character in the column name?

Just to update this for current technologies:
While the JDBC-ODBC Bridge and Access ODBC were unable to handle a PreparedStatement with a column name containing a question mark, the UCanAccess JDBC driver handles it just fine, as can be confirmed with the following code:
String connectionUrl = "jdbc:ucanaccess://C:/Users/Public/UCanAccessTest.accdb";
Connection conn = DriverManager.getConnection(connectionUrl);
String sql = "SELECT ID, [Open?] FROM tblJobList WHERE WeekEnding=?";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setDate(1, java.sql.Date.valueOf("2016-01-01"));
ResultSet rs = ps.executeQuery();
while (rs.next()) {
System.out.printf("%d: %s%n", rs.getInt("ID"), rs.getBoolean("Open?"));
}
conn.close();
For more information on UCanAccess, see
Manipulating an Access database from Java without ODBC

I am not sure but you can try // to escape the special meaning of ? and to use it as a normal character. Like:
"SELECT Open//? FROM tblJobList WHERE WeekEnding=?"
You can get something similar to your problem here:
Round bracket in string with JDBC prepared statement

Escaping quotes in MSSQL is done by a double quote, so a '' or a "" will produce one escaped ' and ", respectively.

Problem with special characters and preparedStatement, ONLY if I use setString

I've read many threads regarding this topic, but everybody point to the character set in the database.
I'm using strings with special characters like 'ñ' and I'm not able to set them right in the database. As you may guess, the characters are changed to '?'.
The thing is that using this statement, I get it RIGHT:
stmt = con.prepareStatement("INSERT INTO LONG_CODES_TABLE (TIMESTAMP, TABLE_NAME, CODE__C, CODE_DESC)
VALUES (GET_TIMESTAMP, 'MUNICIPIOS', '" + municipio + "', '" + municipio + "') ");
And just in the same database and table, without changing anything, if I use the following I get the '?' character in the DB:
stmt = con.prepareStatement("INSERT INTO LONG_CODES_TABLE (TIMESTAMP, TABLE_NAME, CODE__C, CODE_DESC)
VALUES (GET_TIMESTAMP, 'MUNICIPIOS', ?, ?) ");
stmt.setString(1, municipio);
stmt.setString(2, municipio);
So, the character problem is happening ONLY if I use setString.
Any ideas?
EDIT: The value of the 'municipio' variable is, for example: 'ABADIÑO'.
Later, I can check the differences between doing it on way or the other by asking for that value with an sql statement, for example:
select * from long_codes_table
where table_name = 'MUNICIPIOS' and code__c = 'ABADIÑO'
One way I get the result row. The other way, I don't.
Thank you.

I had that behaviour, too. On top of that I observed that this error did not occur when the application was started from the IDE. That's how I realized that in the JVM - attributes, the one for the encoding was missing.
