我尝试使用groovy将文件插入到oracle db表中。我使用以下代码:
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:113)
at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331)
at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:288)
at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:754)
at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:219)
at oracle.jdbc.driver.T4CPreparedStatement.executeForRows(T4CPreparedStatement.java:972)
at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1192)
at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3415)
at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:3521)
at InsertUpdate$_run_closure1.doCall(InsertUpdate.groovy:35)
at InsertUpdate.run(InsertUpdate.groovy:23)
执行代码时,我得到以下输出。

2016年12月28日上午11:01:56 groovy.sql.Sql执行 警告:无法执行:INSERT INTO SCM_GROOVY_SCRIPTS (SCRIPT_NAME,SCRIPT_SOURCE,LAST_UPDATED)VALUES(?,?,?)因为: ORA-01461:只能插入一个LONG值才能插入LONG列
Caught:java.sql.SQLException:ORA-01461:只能绑定LONG值 插入LONG栏
java.sql.SQLException:ORA-01461:只能绑定LONG值 插入LONG栏
CREATE TABLE SCM_GROOVY_SCRIPTS ( SCRIPT_NAME VARCHAR2(255) NOT NULL, SCRIPT_SOURCE CLOB, LAST_UPDATED DATE DEFAULT SYSDATE , PRIMARY KEY (SCRIPT_NAME) );
如果我将clob参数传递为null而不是file.bytes,它会插入所有行而不会出现任何错误。我的表结构如下:
Switch(v.getId()){
case R.id.Yourid1:
CountDownTimer test= new CountDownTimer(3000,1000) { //count down from 3 sec to 1 sec
@Override
public void onTick(long millisUntilFinished) {
//do some thing after starting timer
}
@Override
public void onFinish() {
// do something after timer is finished
}
};
test.start();
break;
case R.id.YourId2:
CountDownTimer test1= new CountDownTimer(3000,1000) { //count down from 3 sec to 1 sec
@Override
public void onTick(long millisUntilFinished) {
//do some thing after starting timer
}
@Override
public void onFinish() {
// do something after timer is finished
}
};
test1.start();
}
break;
此外,如果我使用BLOB数据类型而不是CLOB,则代码可以工作。
答案 0 :(得分:0)
最后,我找到了一种插入CLOB数据类型的方法。
解决方案是使用java.sql.Clob和oracle.sql.CLOB类。
import groovy.io.FileType
import groovy.sql.Sql
import oracle.jdbc.OracleDriver
import oracle.sql.CLOB
import java.sql.Clob
import java.sql.Date
final def PROJECT_DIR = "/appdata/project/pmp"
final def SCRIPT_DIR = "/scm/src/main/scripts"
// To be able to use driver...
new OracleDriver();
Sql sql = Sql.newInstance("jdbc:oracle:thin:@localhost:1521:XE", "PMP", "pmp")
sql.execute("delete from SCM_GROOVY_SCRIPTS")
def dir = new File(PROJECT_DIR + SCRIPT_DIR);
dir.eachFileRecurse(FileType.FILES) { file ->
String scriptName = file.name.substring(0, file.name.indexOf('.'))
def timestamp = new Date(System.currentTimeMillis())
println scriptName
println timestamp
Clob clob = CLOB.createTemporary(sql.getConnection(), false, CLOB.DURATION_SESSION);
clob.setString(1, file.getText("UTF-8"))
List<Object> params = new ArrayList<>()
params.add(scriptName)
params.add(clob)
params.add(timestamp)
sql.execute("INSERT INTO SCM_GROOVY_SCRIPTS (SCRIPT_NAME, SCRIPT_SOURCE, LAST_UPDATED) VALUES (?, ?, ?)", params)
}
sql.close()
