@Column(name = "NCLOBTEST", columnDefinition = "nclob")
public String getNclobtest() {
return this.nclobtest;
} |
|
char(n) The CHAR datatype stores fixed-length character strings. When you create a table with a CHAR column, you must specify a string length (in bytes or characters) between 1 and 2000 bytes for the CHAR column width. The default is 1 byte. | - Code Block |
---|
| visitor.addPropertyColumnDefinitionFix(new PropertyColumnDefinitionFix(
new String[]{"CHAR"},new String[]{"java.lang.String"},"char")); |
| Code Block |
---|
| private String chartest; |
Code Block |
---|
| @Column(name = "CHARTEST", length = 10,
columnDefinition = "char")
public String getChartest() {
return this.chartest;
} |
|
varchar The VARCHAR datatype is synonymous with the VARCHAR2 datatype. To avoid possible changes in behavior, always use the VARCHAR2 datatype to store variable-length character strings. | - - | Code Block |
---|
| private String varchartest; |
Code Block |
---|
| @Column(name = "VARCHARTEST", length = 10)
public String getVarchartest() {
return this.varchartest;
} |
|
nvarchar2 NVARCHAR2 is a Unicode datatype that store Unicode character data. The character set NVARCHAR2 datatype can only be either AL16UTF16 or UTF8 and is specified at database creation time as the national character set. AL16UTF16 and UTF8 are both Unicode encoding. | - Code Block |
---|
| visitor.addPropertyColumnDefinitionFix(new PropertyColumnDefinitionFix(
new String[]{"NVARCHAR2"},new String[]{"java.lang.String"},"nvarchar2")); |
| Code Block |
---|
| private String nvarchar2test; |
Code Block |
---|
| @Column(name = "NVARCHAR2TEST", length = 10,
columnDefinition = "nvarchar2")
public String getNvarchar2test() {
return this.nvarchar2test;
} |
|
varchar2 The VARCHAR2 datatype stores variable-length character strings. When you create a table with a VARCHAR2 column, you specify a maximum string length (in bytes or characters) between 1 and 4000 bytes for the VARCHAR2 column. For each row, Oracle Database stores each value in the column as a variable-length field unless a value exceeds the column's maximum length, in which case Oracle Database returns an error. | - - | Code Block |
---|
| private String varchar2test; |
Code Block |
---|
| @Column(name = "VARCHAR2TEST", length = 10")
public String getVarchar2test() {
return this.varchar2test;
} |
|
clob The CLOB datatype stores up to 128 terabytes of character data in the database. CLOBs store database character set data. | Code Block |
---|
| <sql-type jdbc-type="CLOB" hibernate-type="java.lang.String" /> |
Code Block |
---|
| visitor.addPropertyColumnDefinitionFix(new PropertyColumnDefinitionFix(
new String[]{"CLOB"},new String[]{"java.lang.String"},"clob")
.addLobAnnotation()); |
| Code Block |
---|
| private String clobtest; |
Code Block |
---|
| @Lob
@Column(name = "CLOBTEST", columnDefinition = "clob")
public String getClobtest() {
return this.clobtest;
} |
|
number The NUMBER datatype stores fixed and floating-point numbers. Numbers of virtually any magnitude can be stored and are guaranteed portable among different systems operating Oracle Database, up to 38 digits of precision. | Code Block |
---|
| <sql-type jdbc-type="NUMERIC" name="number"
hibernate-type="java.lang.Double" /> |
Code Block |
---|
| visitor.addPropertyColumnDefinitionFix(new PropertyColumnDefinitionFix(
new String[]{"NUMBER"},new String[]
{"java.lang.Double","double"},"number")); |
| Code Block |
---|
| private Double numbertest; |
Code Block |
---|
| @Column(name = "NUMBERTEST", precision = 22,
scale = 0)
public Double getNumbertest() {
return this.numbertest;
} |
|
date The DATE datatype stores point-in-time values (dates and times) in a table. The DATE datatype stores the year (including the century), the month, the day, the hours, the minutes, and the seconds (after midnight). Oracle Database can store dates in the Julian era, ranging from January 1, 4712 BCE through December 31, 9999 CE (Common Era, or 'AD'). Unless BCE ('BC' in the format mask) is specifically used, CE date entries are the default. Oracle Database uses its own internal format to store dates. Date data is stored in fixed-length fields of seven bytes each, corresponding to century, year, month, day, hour, minute, and second. | - - | Code Block |
---|
| private Date datetest; |
Code Block |
---|
| @Temporal(TemporalType.DATE)
@Column(name = "DATETEST", length = 7)
public Date getDatetest() {
return this.datetest;
} |

timestampTIMESTAMP | - - |
| Code Block |
---|
| private Date timestamptest; |
Code Block |
---|
| @Temporal(TemporalType.TIMESTAMP)
@Column(name = "TIMESTAMPTEST")
public Date getTimestamptest() {
return this.timestamptest;
} |
|
blobBLOB The BLOB datatype stores unstructured binary data in the database. BLOBs can store up to 128 terabytes of binary data. | Code Block |
---|
| <sql-type jdbc-type="BLOB" hibernate-type="byte[]" /> |
Code Block |
---|
| visitor.addPropertyColumnDefinitionFix(new PropertyColumnDefinitionFix(
new String[]{"BLOB"},new String[]{"byte[]"},"blob")); | Code Block |
