 1 kettle uses file import to Postgresql to summarize the following kinds of problems.
 2 1, the first error, reported as ERROR: extra data after last expected column shown. Or error is reported as error 0x05, extra data after last expected column.
 3 1), sql query statement to locate a field.
 4 SELECT * from data table name where field name like CONCAT('%',char(5),'%')
 5 2) The solution, using empty substitution, is due to the occurrence of special characters, char(5), such characters, resulting in the error.
 6 The solution is shown below.
 7 public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException { 
 8 Object[] r = getRow();
 9 
10 if (r == null) { 
11 setOutputDone(); 
12 return false; 
13 }
14 
15 // It is always safest to call createOutputRow() to ensure that your output row's Object[] is large 
16 // enough to handle any new fields you are creating in this step. 
17 r = createOutputRow(r, data.outputRowMeta.size());
18 
19 String fieldName = get(Fields.In, "fieldName").getString(r);
20 if(FieldName ! = null) {
21 fieldName = fieldName.replaceAll((char)5 + "", "");
22 }
23 get(Fields.Out, "fieldName").setValue(r, fieldName);
24 
25 // Send the row on to the next step. 
26 putRow(data.outputRowMeta, r);
27 
28 return true; 
29 } 
30 
31 2. The second error, reporting errors such as missing data for column "datastamp".
32 1), sql query statement to locate a field.
33 SELECT * from data table name where field name like CONCAT('%',char(10),'%')
34 Or
35 SELECT * from data table name where field name like CONCAT('%',char(13),'%')
36 2), the solution: is the value of the field appears, carriage return, char(10), char(13). char(10) more than one line, less n columns, missing data column xxx. solution, use the character substitution, and then replace back.
37 The solution is shown below.
38 public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException { 
39 Object[] r = getRow();
40 
41 if (r == null) { 
42 setOutputDone(); 
43 return false; 
44 }
45 
46 // It is always safest to call createOutputRow() to ensure that your output row's Object[] is large 
47 // enough to handle any new fields you are creating in this step. 
48 r = createOutputRow(r, data.outputRowMeta.size());
49 
50 String fieldName = get(Fields.In, "fieldName").getString(r);
51 if(FieldName ! = null) {
52 fieldName = fieldName.replaceAll("\\r", "@#r;");
53 fieldName = fieldName.replaceAll("\\\n", "@#n;");
54 }
55 get(Fields.Out, "fieldName").setValue(r, fieldName);    
56     
57 // Send the row on to the next step. 
58 putRow(data.outputRowMeta, r);
59 
60 return true; 
61 } 
62 
63 3, the third error, the error reported as, 0x00 solution.
64 1), sql query statement to locate a field.
65 SELECT * from data table name where field name like CONCAT('%',char(0),'%')
66 2), solution 1
67 public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException { 
68 Object[] r = getRow();
69 
70 if (r == null) { 
71 setOutputDone(); 
72 return false; 
73 }
74 
75 // It is always safest to call createOutputRow() to ensure that your output row's Object[] is large 
76 // enough to handle any new fields you are creating in this step. 
77 r = createOutputRow(r, data.outputRowMeta.size());
78 
79 // Get the value from an input field 
80 String fieldName = get(Fields.In, "fieldName").getString(r);
81 
82 if(fieldName ! = null) {
83 fieldName = fieldName.replaceAll("\\u0000", "");
84 }
85 
86 get(Fields.Out, "fieldName").setValue(r, fieldName);
87 
88 // Send the row on to the next step. 
89 putRow(data.outputRowMeta, r);
90 
91 return true; 
92 }
