While running spring boot with h2 database and JPA i am getting below error.
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement
at org.hibernate.tool.schema.internal.exec.GenerationTargetToDatabase.accept(GenerationTargetToDatabase.java:67) ~[hibernate-core-5.2.17.Final.jar:5.2.17.Final]
at org.hibernate.tool.schema.internal.SchemaCreatorImpl.applySqlString(SchemaCreatorImpl.java:440) [hibernate-core-5.2.17.Final.jar:5.2.17.Final]
It is caused due to below one
Caused by: org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "CREATE TABLE EXCHANGE_VALUE (ID INTEGER NOT NULL, CONVERSION_MULTIPLE DECIMAL(19,2), FROM[*] VARCHAR(255), PORT INTEGER NOT NULL, TO VARCHAR(255), PRIMARY KEY (ID)) "; expected "identifier"; SQL statement:

My hibernate class
import java.math.BigDecimal;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="Exchange_Value")
public class ExchangeValue {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;
private String from;
private String to;
private BigDecimal conversionMultiple;
private int port;
public ExchangeValue() {
}
public ExchangeValue(String from, String to, BigDecimal conversionMultiple) {
super();
// this.id = id;
this.from = from;
this.to = to;
this.conversionMultiple = conversionMultiple;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
application.properties is below
spring.application.name=currency-exchange-service
server.port=8000
spring.jpa.hibernate.ddl-auto= create-drop
Just want to know as to what i am missing in the code tried adding spring.jpa.hibernate.ddl-auto= create-drop but it did not helped.
@shubh.. Your Entity Field names are matching with SQL reserved keywords
,
So try to change the field names otherwise use name
attribute with @Column Annotation
(which gives alias names to the DATABASE)
@Column(name="valueFrom")
private String from;
@Column(name="valueTo")
private String to;
private BigDecimal conversionMultiple;
private int port;
Your Entity Field name from was matched with database reserved word from, change the field name to another, or add a @Column annotation on that field. Like:
...
@Column(name = "_from")
private String from;
...
