Question

I cannot find any method like

char c = ‘c’;

preparedStatement.setChar(1, c);

How to set character to a prepared statement?

Answer 1

The JDBC Specification 4.0 in Appendix B (Data Type Conversion Tables) states the following conversions:

This table also shows the conversions used by the SQLInput reader methods, except that they use only the recommended conversions.

JDBC Type              Java Type
-------------------------------------------
CHAR                   String
VARCHAR                String
LONGVARCHAR            String
NUMERIC                java.math.BigDecimal
DECIMAL                java.math.BigDecimal
BIT                    boolean
BOOLEAN                boolean
TINYINT                byte
SMALLINT               short

TABLE B- 1  JDBC Types Mapped to Java Types

Therefore PreparedStatement.setString(1, String.valueOf(myChar)) should do the trick.
