pruidong opened a new issue, #9123:
URL: https://github.com/apache/seatunnel/issues/9123
Oracle migrates data to Clickhouse. Some fields in Oracle tables are null
values, and some date fields have the value of 1900-01-01 (ClickHouse only
supports 1970-01-01). Every column in the ClickHouse table is non-null, and
about 40 tables need to be synchronized. Is there any way to solve this
quickly? Thank you.
I tested it once using the following method, but there was no effect:
```
env {
execution.parallelism = 64
log_level = "DEBUG"
}
source {
Jdbc {
plugin_output = "ora_114"
driver = "oracle.jdbc.OracleDriver"
url = "jdbc:oracle:thin:@192.168.6.114:1521:ORCL"
user = "test"
password = "123456"
query = "SELECT * FROM TJ.${table} WHERE ${date_column} BETWEEN
TO_DATE('${start_date}','YYYY-MM-DD') AND TO_DATE('${end_date}','YYYY-MM-DD')"
fetch_size = 20000
}
}
transform {
DynamicCompile {
plugin_input = ["ora_114"]
plugin_output = "setting_default_value"
compile_language="JAVA"
compile_pattern="SOURCE_CODE"
source_code="""

import java.util.ArrayList;
import cn.hutool.json.JSONUtil;
public Column[] getInlineOutputColumns(CatalogTable
inputCatalogTable) {
return new Column[]{};
}
public Object[]
getInlineOutputFieldValues(SeaTunnelRowAccessor inputRow) {
Object[] fieldValues = new Object[2];
System.out.println("-------------------------------------------------------------------------------");
Object ageField = inputRow.getField(1);
System.out.println("-------------------------------------------------------------------------------");
System.out.println(JSONUtil.toJsonStr(inputRow));
System.out.println("-------------------------------------------------------------------------------");
fieldValues[0] = "JAVA";
return fieldValues;
}
