getMaxLength()
public abstract long getMaxLength()Optional. Maximum length of values of this field for STRINGS or BYTES.
If max_length is not specified, no maximum length constraint is imposed on this field.
If type = "STRING", then max_length represents the maximum UTF-8 length of strings in this field.
If type = "BYTES", then max_length represents the maximum number of bytes in this field.
It is invalid to set this field if type is not "STRING" or "BYTES".

| Type | Description |
long | The maxLength. |

string name = 1 [(.google.api.field_behavior) = REQUIRED];
| Returns | |

getNameBytes()
public abstract ByteString getNameBytes()Required. The field name. The name must contain only letters (a-z, A-Z), numbers (0-9), or underscores (_), and must start with a letter or underscore. The maximum length is 128 characters.
string name = 1 [(.google.api.field_behavior) = REQUIRED];
| Returns | |
|---|---|
| Type | Description |
ByteString | The bytes for name. |
getPrecision()
public abstract long getPrecision()Optional. Precision (maximum number of total digits in base 10) and scale (maximum number of digits in the fractional part in base 10) constraints for values of this field for NUMERIC or BIGNUMERIC.
It is invalid to set precision or scale if type is not "NUMERIC" or "BIGNUMERIC".
If precision and scale are not specified, no value range constraint is imposed on this field insofar as values are permitted by the type.
Values of this NUMERIC or BIGNUMERIC field must be in this range when:
- Precision (P) and scale (S) are specified: [-10^(P-S) + 10^(-S), 10^(P-S) - 10^(-S)]
Precision (P) is specified but not scale (and thus scale is interpreted to be equal to zero): [-10^P + 1, 10^P - 1].
Acceptable values for precision and scale if both are specified:
If type = "NUMERIC": 1 <= precision - scale <= 29 and 0 <= scale <= 9.
If type = "BIGNUMERIC": 1 <= precision - scale <= 38 and 0 <= scale <= 38.
Acceptable values for precision if only precision is specified but not scale (and thus scale is interpreted to be equal to zero):
If type = "NUMERIC": 1 <= precision <= 29.
If type = "BIGNUMERIC": 1 <= precision <= 38.
If scale is specified but not precision, then it is invalid.
int64 precision = 8 [(.google.api.field_behavior) = OPTIONAL];
| Returns | |
|---|---|
| Type | Description |
long | The precision. |
getScale()
public abstract long getScale()Optional. See documentation for precision.
int64 scale = 9 [(.google.api.field_behavior) = OPTIONAL];
| Returns | |
|---|---|
| Type | Description |
long | The scale. |
getType()
public abstract TableFieldSchema.Type getType()Required. The field data type.
.google.cloud.bigquery.storage.v1.TableFieldSchema.Type type = 2 [(.google.api.field_behavior) = REQUIRED];
| Returns | |
|---|---|
| Type | Description |
TableFieldSchema.Type | The type. |
getTypeValue()
public abstract int getTypeValue()Required. The field data type.
.google.cloud.bigquery.storage.v1.TableFieldSchema.Type type = 2 [(.google.api.field_behavior) = REQUIRED];
| Returns | |
|---|---|
| Type | Description |
int | The enum numeric value on the wire for type. |
