Using setDate in PreparedStatement
In order to standardize our codebase, we have been tasked with transitioning all instances of hardcoded SQL variables to prepared statements with bound variables. However, we have encountered an issue with the setDate() method.
The code snippet provided is as follows:
DateFormat dateFormatYMD = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); DateFormat dateFormatMDY = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss"); Date now = new Date(); String vDateYMD = dateFormatYMD.format(now); String vDateMDY = dateFormatMDY.format(now); String vDateMDYSQL = vDateMDY; java.sql.Date date = new java.sql.Date(0000-00-00); requestSQL = "INSERT INTO CREDIT_REQ_TITLE_ORDER (REQUEST_ID," + " ORDER_DT, FOLLOWUP_DT) " + "values(?,?,?,)"; prs = conn.prepareStatement(requestSQL); prs.setInt(1, new Integer(requestID)); prs.setDate(2, date.valueOf(vDateMDYSQL)); prs.setDate(3, date.valueOf(sqlFollowupDT));
Upon executing the SQL query, the following error is encountered:
java.lang.IllegalArgumentException at java.sql.Date.valueOf(Date.java:138) at com.cmsi.eValuate.TAF.TAFModuleMain.CallTAF(TAFModuleMain.java:1211)
Solution
The setDate() method requires a valid date value. In this case, we have set it to new java.sql.Date(0000-00-00), which is an invalid date.
To resolve this issue, the following solutions can be considered:
Using java.sql.Date
If the table column has a DATE type, the following options are available:
-
java.lang.String: Use java.sql.Date.valueOf(java.lang.String) to parse the date string in the format yyyy-[m]m-[d]d, e.g.:
ps.setDate(2, java.sql.Date.valueOf("2013-09-04"));
-
java.util.Date: Convert the java.util.Date object using new java.sql.Date(endDate.getTime()), e.g.:
ps.setDate(2, new java.sql.Date(endDate.getTime()));
- Current: Use new java.sql.Date(System.currentTimeMillis()) to insert the current date, or java.sql.Date.valueOf(java.time.LocalDate.now()) in Java 8 and above.
Using java.sql.Timestamp
If the table column has a TIMESTAMP or DATETIME type, the following options are available:
-
java.lang.String: Use java.sql.Timestamp.valueOf(java.lang.String) to parse the date string in the format yyyy-[m]m-[d]d hh:mm:ss[.f…], e.g.:
ps.setTimestamp(2, java.sql.Timestamp.valueOf("2013-09-04 13:30:00"));
-
java.util.Date: Convert the java.util.Date object using new java.sql.Timestamp(endDate.getTime()), e.g.:
ps.setTimestamp(2, new java.sql.Timestamp(endDate.getTime()));
- Current: Use new java.sql.Timestamp(System.currentTimeMillis()), java.sql.Timestamp.from(java.time.Instant.now()), or java.sql.Timestamp.valueOf(java.time.LocalDateTime.now()) in Java 8 and above to insert the current timestamp.
The above is the detailed content of How to Correctly Use setDate() in PreparedStatements to Avoid `java.lang.IllegalArgumentException`?. For more information, please follow other related articles on the PHP Chinese website!

Java is widely used in enterprise-level applications because of its platform independence. 1) Platform independence is implemented through Java virtual machine (JVM), so that the code can run on any platform that supports Java. 2) It simplifies cross-platform deployment and development processes, providing greater flexibility and scalability. 3) However, it is necessary to pay attention to performance differences and third-party library compatibility and adopt best practices such as using pure Java code and cross-platform testing.

Java is suitable for developing cross-server web applications. 1) Java's "write once, run everywhere" philosophy makes its code run on any platform that supports JVM. 2) Java has a rich ecosystem, including tools such as Spring and Hibernate, to simplify the development process. 3) Java performs excellently in performance and security, providing efficient memory management and strong security guarantees.

JVM implements the WORA features of Java through bytecode interpretation, platform-independent APIs and dynamic class loading: 1. Bytecode is interpreted as machine code to ensure cross-platform operation; 2. Standard API abstract operating system differences; 3. Classes are loaded dynamically at runtime to ensure consistency.

The latest version of Java effectively solves platform-specific problems through JVM optimization, standard library improvements and third-party library support. 1) JVM optimization, such as Java11's ZGC improves garbage collection performance. 2) Standard library improvements, such as Java9's module system reducing platform-related problems. 3) Third-party libraries provide platform-optimized versions, such as OpenCV.

The JVM's bytecode verification process includes four key steps: 1) Check whether the class file format complies with the specifications, 2) Verify the validity and correctness of the bytecode instructions, 3) Perform data flow analysis to ensure type safety, and 4) Balancing the thoroughness and performance of verification. Through these steps, the JVM ensures that only secure, correct bytecode is executed, thereby protecting the integrity and security of the program.
